Problema Solution
the perimeter of a rectangle is found by using the formula: 2L+2W. if the perimeter of a rectangle is 66 cm, and the length is twice the width, what is the length?
Answer provided by our tutors
Equation 1: Length is twice the width
L = 2W
Equation 2: Substitute L=2W
2L + 2W = 66
2(2W) + 2W = 66
6W = 66
W = 11cm
Hence,
L = 2(11)
= 22cm
