The rectangle is 300 feet in perimeter and the length is 10 feet less than the width. What are the dimensions of the rectangle?

Question

There is 300 feet of fencing to close a rectangular garden and all 300 feet need used.

Answer 1

Perimeter is twice the sum of length and width, so length+width=150 feet.

Length is width-10 so width-10+width=150, 2*width=160, width=80 feet and length is 70 feet.
