Answer:
Step-by-step explanation:
Width = w units
Length = ( w + 13 ) units
Perimeter of rectangle = 38 units
2* (length + width) = 38
2*(w +13 + w )= 38 {Use distributive property: a*(b+c)=(a*b) +(a*c)
2* ( 2w + 13) = 38
2*2w + 2*13 = 38
4w + 26 = 38 {Subtract 26 from both sides}
4w = 38 - 26
4w = 12 {Divide both sides by 4}
w = 12/4
w = 3 units
Length = 3 + 13 = 16 units
