Question

"the fromula for the perminter of a rectangle is given by P= 2L +2W where l is the length and w is the width. Assume the ermiter of a rectangular plot of land is 480 ft. The length is twice the width. Find the length of rectangular plot of land

Answer 1

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.
