Let the length of the rectangle be L and the width be W. But we know that the perimeter is 36. Now we will calculate the area: ==> A = L * W = 12* 6 = 72 square feet.

Expert Answers Hover for more information. The dimensions of a rectangle with perimeter 36 cm have to be determined that maximize the area without using calculus. The length of the required rectangle has a length equal to 9 and the width is 18 – 9 = 9.

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Perimeter of the field is given as Perimeter = 2(Length + Breadth) and it is 150 cm.

If perimeter = 36, for a square each side length would be 36/4=9 units. So area is 9 x 9 =81 squared units.

Length is the distance from one end to the other end of an object, while the width is the distance from side to side. Length is a type of measurement that shows how tall or long an object is. Width is a type of measurement that shows how wide an object is.

To find Length or Breadth when Area of a Rectangle is given

1. When we need to find length of a rectangle we need to divide area by breadth.
2. Length of a rectangle = Area ÷ breadth.
3. ℓ = A ÷ b.
4. Similarly, when we need to find breadth of a rectangle we need to divide area by length.
5. Breadth of a rectangle = Area ÷ length.

To get the perimeter from the area for a square, multiply the square root of the area times 4 . Perimeter is always measured in linear units, which is derived from the area’s square units.

What is the difference between the perimeter and area of a shape? The perimeter is the sum of all the side lengths of a shape. The area is the amount of two dimensional space a shape occupies.

Area of a Circle. The area of a circle is given by the following formula: A=πr2 where r is the radius of the circle. What is a radius? It’s the distance from the center of the circle to any point on the edge of the circle. The radius will always be the same length!

The area of a circle is pi times the radius squared (A = π r²).

Perimeter is the distance around the edge of a shape. Learn how to find the perimeter by adding up the side lengths of various shapes.

How to find perimeter?

Perimeter of a Rectangle = 2 (L+B) = 2 (6 cm + 4 cm) = 2 × 10 cm = 20 cm….Area and Perimeter Formula Chart.

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
