Question

The length of a rectangle is 15 feet and the perimeter is 62 feet. Write the equation that you would use to find the width of the rectangle. Solve the equation explaining the steps you use to solve the equation.

Answer 1

L=15 , W=?, p=62

so perimeter formula for rectangle is L+L+W+W=62 or 2L+2W=62. And we knew that L is 15 so the equation is 2(15)+2w=62 . 2w=62-30, 2w=32 and divide both both side by 2 and you get 16.
