Question

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

Answer 1

Answer:

1.292 x 10^7 cm^2

Step-by-step 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:

$L=\frac{A}{W}\\L=\frac{2.76 \times 10^{12}}{4.6 \times 10^5}\\L = 6 \times 10^6$

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:

$P = 2(6 \times 10^6) + 2(4.6 \times 10^5)\\P = 1.292 \times 10^7$
