Answer:

15m by 25m

Step-by-step explanation:

(1) Represent the variables

width (w) = w

length (l) = w + 10

Perimeter (P) = 80m

(2) Identify the formula to be used and simplify after substituting the variables to get the value of w

P = 2l + 2w

80 = 2(w + 10) + 2(w)

80 = 2w + 20 + 2w

80 = 4w + 20

60 = 4w

w = 15

(3) Substitute w = 15 to the length and width

width (w) = w = 15 m

length (l) = w + 10 = 15 + 10 = 25 m
