Question B. Find the width of a rectangle if its length is 5 more than the width and its perimeter is 90 cm.

Answer: Width is 20cm Step-by-step explanation: Step one: Given data let the width be x W= x L= x+5 P= 90 Step two: The expression for the perimeter is P= 2L+2W 90= 2*x+2(x+5) 90= 2x+2x+10 collect like terms 90-10=4x 80= 4x divide both sides by 4 x= 80/4 x= 20 Log in to Reply

Answer:Width is 20cm

Step-by-step explanation:Step one:

Given data

let the width be x

W= x

L= x+5

P= 90

Step two:

The expression for the perimeter is

P= 2L+2W

90= 2*x+2(x+5)

90= 2x+2x+10

collect like terms

90-10=4x

80= 4x

divide both sides by 4

x= 80/4

x= 20
