If the length of a rectangle is 3 feet longer than the width and

the diagonal I s 15 feet, then what are the length and width?

**PsyDAG**, Monday, November 23, 2009 at 10:42amUse the Pythagorean theorem.

Hypotenuse^2 = sum of squares of other two sides

Let x = length, then width = x - 3

15^2 = x^2 + (x-3)^2

Does this help?
