Answer:
Step-by-step explanation:
The formula for the perimeter of a rectangle is ...
P = 2(L+W)
If the length is 30 yards more than the width, we can use L = W+30 and substitute known values into the above formula:
300 = 2((W+30) +W)
150 = 2W +30 . . . . . divide by 2 and collect terms
120 = 2W . . . . . . . . . subtract 30
60 = W . . . . . . . . . . . divide by 2
60+30 = L = 90
The length is 90 yards; the width is 60 yards.
