Question

Find length and width of retangle when legnth is 2 times width and area is 48 square inches

Answer 1

The area of a rectangle = width * length

length = 2*width => l = 2*w

2*w*w = 48

w^2 = 24

w = square root of 24 = 2 * sqrt(6)

l = 2*w = 4*sqrt(6)

Width is 2*sqrt(6) and the length is 4*sqrt(6).
