Answer 1

L= 10 in

W= 7 in

Explanation:

Given data

let the widht be x

W= x

L= x+3

P=34 in

We know that

P=2L+2W

34= 2(x+3)+ 2(x)

34= 2x+6+2x

collect like terms

34= 4x+6

34-6= 4x

28= 4x

divide both sides by 4

x= 28/4

x=7

Put x= 7 in

L= x+3

L= 7+3= 10

Hence the width is 7in the length is 10 in
