given

let the width be x

W=x inches

L= 2x+3 inches

perimeter= 96inches

Step two:

Required

the dimensions of the rectangle

The perimeter is

P=2L+2W

96=2(2x+3)+2(x)

open bracket

96=4x+6+2x

collect like terms

96-6=6x

90=6x

divide both sides by 6

x=90/6

x=15 in

The width is 15 in

The length

L=2x+3

L=2(15)+3

L=30+3

L=33in
