Question

The perimeter of a rectangle is 110, and the width is 4 times

the length. What is the width?
O 33
O 44
O 66
O 55

Answer 1

44

Explanation:

come on now.

the perimeter is

2×length + 2×width = 110

width = 4×length

so, we use the second equation in the first :

2×length + 2×(4×length) = 110

2×length + 8×length = 110

10×length = 110

length = 110/10 = 11

width = 4×length = 4×11 = 44
