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 *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.
