Answer:
6 cm and 24 cm
Step-by-step explanation:
A rectangle is 4 times as long as it is wide. If its perimeter is 60 cm, find its dimensions.
Set it up as an equation using the perimeter formula (2L + 2W)
We know from the sentence that length is 4 times width so L = 4W
Plug that into the formula and solve for W
2(4W) + 2W = 60
8W + 2 W = 60
10W = 60
W = 60:10
W = 6 cm
l = 6 * 4 = 24 cm
