Given:
Perimeter of a rectangle = 108 inches
length = 34 inches
Find the width.
Perimeter of a rectangle formula: P =2(l+w)
Solution:
Solve the equation of the width of the rectangle, in terms of perimeter.
P =2(l + w)
p/2 -l =w
Substitute the given values of the length and the perimeter to the formula of the width.
w = 108/2 -34
w = 54 - 34
w = 20
The width of the rectangle is 20 inches.
