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

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:

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:

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
