The length of a rectangle is 2 cm more than twice its width. If the perimeter of the rectangle is 52 cm, find the dimensions of the rectangle.
You already know that L=2w+2. So, put this into the formula for perimeter:
Multiply:
Add:
Subtract 4 from both sides:
Divide both sides by 6:
Now you know the width. To find the length, use L=2w+2.
Multiply:
Add:
So, the length is 18, and the width is 8.
