Answer:

264 cm^2

Explanation:

Area of a trapezoid = 1/2 (b1+b2) *h

The area of the large trapezoid

b1 = 14 b2 = 25 h = 10+12 = 22

A = 1/2 (14+25) *22 = 429 cm^2

The area of the unshaded trapezoid

b1 = 8 b2 = 25 h = 10

A = 1/2 (8+25) *10 = 165 cm^2

To find the area of the shaded region, take the area of the large trapezoid and subtract the unshaded trapezoid

429 - 165 =264 cm^2
