The length of a rectangle is 8 feet longer than the width. If the perimeter is 80 feet, find the length and width of the rectang
le
1 answer:
perimeter = 2L + 2W
L=8+w
perimeter = 2(8+w) +2w
80 =16+2w+2w
80 = 16 +4w
64 =4w
w=64/4 = 16
l=16+8 =24
length = 24 feet
width = 16 feet
check 2(24) +2(16) = 48 + 32 = 80
