Answer:
The length of rectangular plot of land is 160 ft.
Explanation:
L = 2 W (the length is twice the width)
P = 480 ft. (perimeter of rectangular plot of land)
L = ?
2. 2W + 2W= 480 ft >>> (2 times twice width=L) + 2W=480 ft.
4W + 2W= 480 ft >>>> 6W= 480 ft.
W= 80 ft.
L = 2. 80 = 160 ft. (Length is twice the width)
P= 2L + 2W (formula for the perimeter)
2. 160 + 2. 80 = 480 ft.
