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!
