Incorrect. Set the width of the border to x. Find the area of the blanket (with border) by multiplying its width $\displaystyle{\left({6}+{2}{x}\right)}\usepackage{cmbright}\Huge\$ by its height $\displaystyle{\left({5}+{2}{x}\right)}\usepackage{cmbright}\Huge\$ . The area of the border is given by the equation $\displaystyle{\left({5}+{2}{x}\right)}{\left({6}+{2}{x}\right)}-{\left({5}\right)}{\left({6}\right)}={12}\usepackage{cmbright}\Huge\$ . Rewrite this as a trinomial, and then solve the trinomial for x.
