Parallelogram
A = bh = 32 x 12 = 384

Triangle
A = 1/2bh = 1/2 x 32 x 12 = 384/2 = 192

384 + 192 = 576
answer
B. 576 ft^2

This is just the area of a triangle and a trapezoid (which have to equal bases in this case) so

A=bh/2+h(b1+b2)/2 in this particular case:

A=32*12/2+12(32+32)/2

A=32*6+12*32

A=576ft^2
