Answer:
length = 63 ft; width = 10.5 ft
Step-by-step explanation:
Let the width be x.
The length is 6 times the width, so the length is 6x.
The perimeter is the sum of 2 lengths and 2 widths.
6x + 6x + x + x
The perimeter equals 147 ft.
6x + 6x + x + x = 147
14x = 147
x = 10.5
The width is 10.5 ft.
The length is 6x, so the length is 6 * 10.5 ft = 63 ft
