Question

Find the perimeter of a rectangle of A=2.76x10^12cm^2 and one side is 4.6x10^5

Answer 1

1.292 x 10^7 cm^2

Explanation:

Since the area of a rectangle is A = L x W and you are given the area and one side, you can rearrange this equation to solve for the other:

`L=(A)/(W)\\L=(2.76 * 10^(12))/(4.6 * 10^5)\\L = 6 * 10^6`

Therefore the length of the other side is 6 x 10^6.

The perimeter of a rectangle is P = 2L + 2W. We can solve that now that we have the length of the sides:

`P = 2(6 * 10^6) + 2(4.6 * 10^5)\\P = 1.292 * 10^7`
