The formula for finding the area of a square is:
[tex] {s}^{2} [/tex]
The formula for finding the area of a triangle is:
[tex] \frac{1}{2} bh[/tex]
So for the square the area would be:
[tex] {2x}^{2} \times {2x}^{2} = {4x}^{2} [/tex]
The area for the triangle would be:
[tex] \frac{1}{2} {2c}^{3} \times 4c = {4c}^{2} [/tex]
