Answer:
W=22.5in
L=25.5in
Step-by-step explanation:
given data
let the width be x
W=x
L=x+3
the perimeter= 96in
the expression for perimeter is
P=2L+2W
Step two:
substitute
96=2(x+3)+2(x)
solve for x
96=2x+6+2x
96=4x+6
96-6=4x
rearrange
4x=90
divide both sides by 4
x=90/4
x=22.5
The width W=22.5in
the length L=22.5+3
L=25.5in
