The length of a rectangle is three times its width. If the area of the rectangle is 192 ft^2, find its perimeter

Blababa [14]

Answer: 64 feet.

Explanation:
Perimeter formula: 2l + 2w
Area formula: l•w
Length = 3w
Area = 192 ft $^{2}$
192 = (3w) • w
192 = 3 $w^{2}$
192 ÷ 3 = 3 $w^{2}$ ÷ 3
64 = $w^{2}$
$\sqrt{64}$ = $\sqrt{ w^{2} }$
8 = w

Width = 8
Length = 3(8) = 24
Perimeter = 2(24) + 2(8) = 64 feet.
