A rectangle is 4 times as long as it is wide. If its perimeter is 60 cm, find its dimensions.

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

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
