The question is in the attached. be for real and not put anything just to get points . i will report if you do.

The perimeter is the sum of all the sides.
So for a rectangle, the perimeter will be (l + l + w + w) or 2(l + w), where l is the length and w the width.

l = 100 ft
w = 140 ft
P = 2(100 + 140)
P = 2(240)
P = 480 ft

C. 480 ft

The percent discount was 120

Look i don’t know the answer to this but someone else will so just wait a little bit longer
