Question

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

the length. What is the width?
33
044
O 66
O 55

Answer 1

with = 44

Explanation:

let the lenght l, = x

b or width = 4x

Perimeter of rectangle = 2(l + b)

110 = 2( x + 4x )

110 = 2( 5x )

110 = 10x

10x = 110

x = 110/10

x = 11

Therefore width = 4x

width = 4 (11)

with = 44

Answer 2

width = 44

Explanation:

let l be length then width = 4l

the perimeter (P) of a rectangle is calculated as

P = 2(l + w)

given P = 110 , then

2(l + 4l) = 110 ( divide both sides by 2 )

l + 4l = 55

5l = 55 ( divide both sides by 5 )

l = 11

then

width = 4l = 4 × 11 = 44
