Question

The length of a rectangle is 4 inches more than its width, and its perimeter is 34 inches. Find the length and width of the rectangle.

If w = the width of the rectangle, then the length equals _____.

Answer 1

\[l=w+4\] where l is length and w is width. The perimeter of a rectangle is given by \[P=2l+2w\] Substituting\[34=2(w+4)+2w\]Solve for w. Plug back into first equation to solve for l
