Question

The width of a Rectangle is 3.6 inches and the perimeter is 72 inches. What is the length of the rectangle?

Answer 1

We know that

• The width of the rectangle is 3.6 inches.

,

• The perimeter is 72 inches.

The perimeter formula for a rectangle is

`P=2(w+l)`

Where P = 72, w = 3.6, and we have to solve for l.

`\begin{gathered} 72=2(3.6+l) \\ (72)/(2)=3.6+l \\ 36=3.6+l \\ l=36-3.6 \\ l=32.4 \end{gathered}`

Therefore, the length of the rectangle is 32.4 inches.
