• For a performance at an outdoor​ event,

a folk music group rented a tent with a bottom shaped like a triangle.

The base of this triangle was 40 ft and the height was 13 and one-half ft,​and it was placed in a corner of a small park that measured 150 ft by 150 ft. How much of the park space was left for the​ audience?

• You have a triangle within a square.  You want the are of the square that isn't taken up by the triangle. So, find the area of both and subtract out the area of the smaller:

A = s² and A = bh/2

A = 150² and A = 40(13.5)/2

A = 22500 and A = 270

subtract the smaller from the larger:

22500 - 270 = 22,230 ft² is left for the audience.
