# How many rectangles have a perimeter 40?

## How many rectangles have a perimeter 40?

Given, Perimeter as 40 cm and (15 cm + 5 cm)*2 = 40 cm. = 75 .

What is the length of a rectangle if the perimeter is 36?

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.

### What are the side lengths of a rectangle?

A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side.

How is the perimeter of a rectangle calculated?

A rectangle has four sides, with opposite sides of the same length. The area of a rectangle is calculated by multiplying the length times the width and can be represented as follows: The perimeter of a rectangle is calculated by adding all the side lengths together.

#### Are there any integer solutions for equable rectangles?

Therefore, all equable rectangles have a length and width relationship of L = 2W / (W – 2) , in which there are infinitely many possibilities. However, there are only 2 integer solutions for an equable rectangle – the 4 x 4 rectangle (which is also an equable square and described above) and the 3 x 6 rectangle.

Which is more difficult to find a square or a rectangle?

Finding an equable rectangle is slightly more difficult than finding an equable square or circle because there are two variables instead of one – length and width. The perimeter of a rectangle with width W and length L is P = 2W + 2L, and the area is A = LW. Therefore,

## Is the perimeter and area of an equable circle the same?

An equable circle has the same numerical perimeter and area, so C = A. Therefore, Of course, a circle cannot have a radius of r = 0, so there is only one equable circle – a circle with a radius of r = 2. Such a circle has both a perimeter and area of 4π (C = 2πr = 2π2 = 4π and A = πr 2 = π2 2 = 4π).
