find the area : 15in 44in 18in 22in
a 165in²
b 495in²
c 330in²
d 594in²

Area of a trapezoid: 1/2(a + b)*h, where a and b are the lengths of the two bases of a trapezoid and h is the height.
Plug 22 and 44 for a and b, respectively. Plug 15 for h.
1/2(22 + 44)*15
1/2(66)*15
1/2(990) = 495
b) 495 in²
