Answer:

Length = 52m Width = 25m

Step-by-step explanation:

P = 2L + 2W = 154 meters

L = 2W + 2 Substitute and solve.

2(2W + 2) + 2W = 154 remove parentheses and combine like terms

4W + 4 + 2W = 154

6W + 4 = 154. Subtract 4 from both sides

6W = 150. Divide both sides by 6

W = 25 m

Therefore: L = 2W + 2 = 2(25) + 2 = 52m

check: P = 2(52) + 2(25) = 104 + 50 = 154m OK
