Question 1074992: two similar trapezoids have heights of 8 centimeters and 12 centimeters. If the area of the smaller trapezoid is 112 square centimeters, what is the area of the larger trapezoid in square centimeters?

The area is directly proportional to the height, so if the height is increased 50%, so is the area, by 56 cm^2 to 168 cm^2.
OR
A=(1/2)h(b1+b2)
224=8 (b1+b2)
28=b1+b2
A=(1/2)*12(28)=168 cm^2
