120 m

Step-by-step explanation:

.

Answer 2

Answer:

length = 20m

width = 10m

Step-by-step explanation:

perimeter = 2 (length + width)

length = 2 * width = 2w

perimeter = 2 (2w +w)

perimeter = 2(3w)

60m = 6w

(divide both sides by 6)

60/6 = w

width = 10m

length = 2w

so length = 2 * 10 = 20m
