To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
What is area formula?
| 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 the formula of area of the rectangle?
The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width. Given that, the area is 500 square feet and the width is 20 feet.
What is the area of the biggest rectangle?
As shown with the algebraic proof using differentiation, the square of 25m x 25m gives the biggest area.
What is the area of the rectangle ABCD?
The area of a rectangle ABCD is the total number of unit squares contained within it . Thus, the total area of the rectangle ABCD is 48 sq. inch. Also, using this approach, we find that the area of a rectangle is always the product of its two sides.
What is area example?
Area is a measure of how much space there is on a flat surface . ... 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.
How do we calculate area?
We measure area in square units : cm2 or m2. Area is calculated by multiplying the length of a shape by its width . In this case, we could work out the area of this rectangle even if it wasn’t on squared paper, just by working out 5cm x 5cm = 25cm2 (the shape is not drawn to scale).
What shape gives the most area?
The circle has the largest area of any two-dimensional object having the same perimeter. A cyclic polygon (one inscribed in a circle) has the largest area of any polygon with a given number of sides of the same lengths.
Why is the area of a square bigger than the area of a rectangle?
Let’s says the rectangle has sides of length A and B and the square has sides of length C. Because they have the same perimeter we can say A+B=2C . so the area of the square will be greater than that of the rectangle by the square of difference of the sides length.
How do you find the area of ABCD?
Its area A can be calculated using the formula A = bh . Figure 15.12 Parallelogram ABCD has an altitude of length h and a base of length b. Example 6: Find the area of the parallelogram in Figure 15.12 if AD = 14 and BE = 5.
Is area a square?
Area is measured in “square” units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side . Since each side of a square is the same, it can simply be the length of one side squared.
What are the formulas for area and perimeter?
| Figures Area Formula Variables | Area of Rectangle Area = l × w l = length w = width | Area of Square Area = a 2 a = sides of the square | Area of a Triangle Area = 1/2 b×h b = base h = height | Area of a Circle Area = πr 2 r = radius of the circle |

How do u find the mean?
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count .
