Question

The length of a rectangle is 3 inches more than its width, and its perimeter is 22 inches. Find the width of the rectangle

4 in.
5 in.
7 in.

Answer 1

First - the perimeter of a rectangle is 2(l + w)
Let's say that the width is x, then the length would be x + 3.
Substitute and equate.

\( \color{Black}{\Rightarrow 2(x + (x + 3)) = 22}\)
Dividing both sides by 2 is a good start.

\( \color{Black}{\Rightarrow x + (x + 3) = 11}\)

combine the like terms.
\( \color{Black}{\Rightarrow 2x + 3 = 11 }\)
Can you do it now?

Answer 2

x=4
