Answer:
Step-by-step explanation:
The product of length and width is the area, 60 m². The width is 4 more than the length, so we need factors of 60 that differ by 4.
60 = 1·60 = 2·30 = 3·20 = 4·15 = 5·12 = 6·10
The last pair of factors, 6 and 10, differ by 4.
The width is 10 meters; the length is 6 meters.
