Question

What is the trinomial that represents the area of a rectangular rug whose sides are (x+3) feet and (2x-1) feet?

Answer 1

`2x^2+5x-3`

Explanation:

Area of a rectangle is length `xx` breadth.

So in this case the area would be

`(x+3)*(2x-1)`

This we can multiply out to obtain

`2x^2+5x-3`.
