The length of a rectangle is three times it’s width. the area of the rectangle is 48 square centimeters. find the measures of the sides.

Define length and width

Let the width be x
Width = x
Length = 3x


Form equation and solve for x

x(3x) = 48
3x² = 48
x² = 48 ÷ 3
x² = 16
x = √16
x = 4


Find length and width

Width = x = 4
Length = 3x = 3(4) = 12


Width = 4cm, Length = 12cm
