Question

A rectangle has length $(7x+4)$ cm and width $(3x+5)$ cm. A triangle has base $(6x-2)$ cm and perpendicular height $(2x+1)$ cm. Find the difference, rectangle area minus triangle area, in the form $ax^2+bx+c$. Assume all dimensions are positive. $(7x+4)\text{ cm}$ $(3x+5)\text{ cm}$ $(6x-2)\text{ cm}$ Height $(2x+1)\text{ cm}$

Accepted Answer

$15x^2+46x+21\text{ cm}^2$.
