Patchwork. A quilt patch cut in the shape of a triangle has a base of 5x inches and a height of 1,732x inches. What polynomial represents its area?

Answer:

Area of triangle is ½*b*h

B=5x

H=1732x

A=1/2*5x*1732x=4330x^2

A=L*W

L=2x-1

W=x+12

A=(2x-1)*(x+12)

A=2x^+24x-x-12=2x^2+23x-12

I need to know if this is done correctly.
