3-96.

The length of a rectangle is three centimeters more than twice the width. The perimeter is $78$ centimeters. Define a variable and write and solve an equation to find out how long and how wide the rectangle is.

Try making a table. See problems 3-6 and 3-41.

Remember that the perimeter is the sum of ALL the sides. Try writing an equation for this situation.

$2\text{L}+2\text{W}=78\text{cm}$

Remember that the length is three centimeters more than twice the width. That is, L $=3+2$W.

Length $=27$ cm
Width $=12$ cm
