Answer:

Explanation:

This is a trapezoid which has an area of

A=h(b2+b1)/2 (average of parallel bases times the height)

The tricky part is finding the height.

tan(90-62)=(9-8)/h

h=1/(tan(28)), now the area equation looks like

A=(b2+b1)/(2(tan28)), b1 and b2 are 8 and 9 so

A=17/(2tan28) ft^2 (exact)

A=15.99 ft^2 (to the nearest hundredth of a square foot)

They might just round it to 16 ft^2
