Question 169538
A rectangular parking lot is 100 ft longer than it is wide. Determine the dimensions of the parking lot if it measures 500 ft diagonally. 

length = x + 100 feet

width = x feet

I will set it up and you can finish.

The diagonal length = 500 feet

Use the Pythegorean Theorem.

(x)^2 + (x + 100)^2 = (500)^2

When you find x, plug your answer for x to find the length and width.

Can you take it from here?

If not, write back.
