Answer:
L= 10 in
W= 7 in
Step-by-step 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
