The area of a rectangular rug is given r squared minus 2r minus 15. What are the possible dimensions of the rug? Use factoring The length and width of the rectangle are?

First of all, we have to find the roots of the polynomial:

So, the two solutions are

And we can use them to factor the polynomial as

So, we have written the area as the product of two dimensions, which means that the length and the width of the rectangles are and .

This implies that has to be at least 5, otherwise you'd have negative dimensions.

the correct is answer is a 9-sided polygon!

a box 3 3/4 feet long or 4+ feet.
