Problema Solution
the width is half as long as the length in a rectangle. The perimeter is 45 inches. What is the width
Answer provided by our tutors
Let
x = the length of the rectangle
x/2 = the width of the rectangle
P = 45 in is the perimeter
P = 2width +2length
P = 2*(x/2) + 2x
P = 3x
3x = 45 divide both sides by 3
x = 45/3
x = 15 in
The width is 15 inches.
