Answer:

Width: 255 feet

Length: 180

Step-by-step explanation:

Hi there!

Perimeter = 2 × width + 2 × length

Let w be equal to the length of the base

Plug in the given information:

870 = 2 × w + 2 × (w-75)

870 = 2w+2w-150

870 = 4w-150

4w=1020

w=255

Therefore, the width of the base is 255 ft.

To find the length of the base, subtract 75 from 255:

255-75 = 180

I hope this helps!
