a rectangle of perimeter 48 miles has a length which is 4 miles more than the width. find the length and width.
Formula:
P = 48 miles
L = 4 +w
W = ?
P = 2(l + w)
48 miles = 2( (4+w)+w)
48 miles = 2(4+w) + 2w
48 miles = 8 +2w + 2w
48-8 = 4w
40 = 4w
40/4 = w
W = 10
L = 4 +w
L = 4 +10
L= 14
Checking:
P = 2(L+W)
48= 2(14 + 10)
48=2(24)
48=48
