What is the area formula and example?
Area Formula
For example, if you want to know the area of a square box with side 40 cm, you will use the formula: Area of Square = a2, where a is the side of the square. Similarly, the area of a triangle can also be found using its Area formula (1/2 × b ×h).
What is a formula of area of square?
In geometry, the square is a shape with four equal sides. The area of a square is defined as the number of square units that make a complete square. It is calculated by using the area of square formula Area = s × s = s2 in square units.
What is area example?
For example, in a rectangle we find the area by multiplying the length times the width. In the rectangle above, the area is 2×4 or 8. If you count the small squares you will find there are 8 of them.
What are units for area?
The SI unit of area is the square meter (m2), which is a derived unit.
How do you write an area?
Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
How do I calculate lot area?
Multiply the length of the base, b, by the height, h, to find the total area. The equation for the area, A, of a square or rectangle area can be written as: A = b * h. In our example, the base, b, is 12 inches, and the height, h, is 5 inches. Therefore, the area is 12 inches multiplied by 5 inches, or 60 square inches.
How fo you find the area of a rectangle?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
What is the area of a 4cm square?
Consider a square that has a side-length of 4 cm. Using the method of counting squares, we find that the area of the square is 16 cm2.
How do you find the area of a square and rectangle?
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.
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.
What does area mean in math?
The area is the amount of space within the perimeter of a 2D shape. It is measured in square units, like cm², m², etc. To find the area of a quadrilateral, you have to multiply the length by the width.
What is called area?
Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
What is the formula for area of all shapes?
Perimeter, Area, and Volume
| Table 2. Area Formulas | ||
|---|---|---|
| Shape | Formula | Variables |
| Square | A=s2 | s is the length of the side of the square. |
| Rectangle | A=LW | L and W are the lengths of the rectangle’s sides (length and width). |
| Triangle | A=12bh | b and h are the base and height |
What is triangular area?
The area of each triangle is one-half the area of the rectangle. So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
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 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.
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).
