Question

The perimeter of a rectangle is calculated by adding together the

measurements of all four sides. For a given rectangle, the length measures
twice the width. If the rectangle's perimeter is 48 in, what does the length
measure in inches?

Answer 1

Let’s say
Length= L
Width= W
L=2w

L+L+w+w=48 = 3L=48
48/3=16
L=16
W=8
