To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

How do you find an area of a square?
How to find the area of a square – formulas. The area of a square is the product of the length of its sides: area = a * a = a² , where a is a square side.
How do we calculate area?
L is the length, W is the width and H is the height. A is the area of the base, h is the height. A is the area of the base, h is the height.
Perimeter, Area, and Volume.

| Shape | Formula | Variables |
| Square | A=s2 | s is the length of the side of the square. |
Why is the area of a square?
A square is a 2D figure in which all the sides are of equal measure. Since all the sides are equal, the area would be length times width, which is equal to side × side. Hence, the area of a square is side square.
How do you find the area of a house shape?
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
What is the area of a 4cm square?
The area of a square is equal to side into side. If the side of the square is equal to 4 cm then the area of square will be side into side that is 4 x 4 equal to 16 centimetre square.
What is the formula for area of a square and rectangle?
For example, the area of a square can be calculated using $a^{2}$ where a is the length of its side.
Area Formulas.
| Figures | Formula | Variables |
|---|---|---|
| Rectangle | Area = l $times$ w | l = length w = width |
| Square | Area = $a^{2}$ | a = sides of square |
| Triangle | Area = $frac{1}{2}$bh | b = base h = height |
How do you find the area of all shapes?
How to calculate area?
- Square area formula: A = a²
- Rectangle area formula: A = a * b.
- Triangle area formulas: A = b * h / 2 or.
- Circle area formula: A = πr²
- Circle sector area formula: A = r² * angle / 2.
- Ellipse area formula: A = a * b * π
- Trapezoid area formula: A = (a + b) * h / 2.
- Parallelogram area formulas:
Can you calculate area from perimeter?
What is its area? Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 ÷ 4 = 3.5.
Are perimeter and area the same for a square?
There are different units for perimeter and area The perimeter has the same units as the length of the sides of rectangle or square whereas the area’s unit is squared.
Is the perimeter same as area?
Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.
What is the area of 10cm and 5cm?
To find the area, you multiply the length and the width. In this case, you multiple 10cm (length) by 5cm (width) to get 50 cm squared as the area. 10 x 5 = 50.
What is the area of a 5cm square?
Square the length of the side. Now that you know that the length of a side is 5 centimeter (2.0 in), you can square it to get the area of the square. Area = (5 cm)2 = 25 centimeter (9.8 in).
What is the area of 7cm?
The area of a square is A = s², where s is the length of one of the 4 congruent sides of the square. A = 49 cm² is the area of a square of side 7 cm in length.
How do you find the area of a shape with 4 different sides?
Use the following equation: Area = side × side or A = s. Example: If one side of a square has a length of 4 feet, (t = 4), then the area of this square is simply t2, or 4 x 4 = 16 square feet.
Parallelograms include:
- Squares: Four sides, all the same length.
- Rectangles: Four sides; opposite sides have same lengths.
How do you calculate the square footage of a shape?
How to Calculate the Square Feet of Odd Shapes
- Measure all the dimensions or sides of the area.
- Draw the area on graph paper using the measurements you obtained.
- Divide the drawing into shapes.
- Figure the area of each shape.
- Add the areas of all the individual shapes to find the total square footage.
How do you find the area of a room?
Calculate the Area as Square Footage
If you are measuring a square or rectangle area, multiply length times width; Length x Width = Area.
What are the formulas for area and perimeter?
Area and Perimeter Formula Chart
| Figures | Area Formula | Variables |
|---|---|---|
| Area of Rectangle | Area = l × w | l = length w = width |
| Area of Square | Area = a2 | a = sides of the square |
| Area of a Triangle | Area = 1/2 b×h | b = base h = height |
| Area of a Circle | Area = πr2 | r = radius of the circle |
What will be the length of the side of a square if it’s area and perimeter are same?
If the perimeters of a square and rectangle are equal, then: 4s = 2(l+w), where s is the side length of the square (since all sides are equal), and l and w are length and height.
