Question 1024817
.
The Browns installed 96 feet of fencing around a rectangular play yard. If the yard covers 540 square feet, what are its dimensions?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
L + W = {{{96/2}}} = 48.
L*W = 540,

where L is the length and W is the width.

---> L = 48-W.

Substitute it into the second equation for L. You will get a single equation for W:

(48-W)*W = 540.

Simplify and solve this quadratic equation by any method.

<U>Answer</U>. L = 30 ft, W = 18 ft.
