Question

rectangular stage that is 9 feet wide has an area of 252 square feet. What is the perimeter of the stage?

Answer 1

Hi there!

First, we need to find the length of the stage. We can do this by plugging in our known values and solving for the unknown value.

WORK:
252 = 9 x l
l = 28

Next, we know that there are two lengths and two widths total. So all we need to do is to add two lengths plus to widths to find the perimeter.

WORK:
2(28) + 2(9) = P
56 + 18 = P
P = 74 feet^2

Hope this helps!! :)
