Answer:

C. 40.5 cm²

Step-by-step explanation:

Use the formula for the area of a trapezoid:

A = (1/2)(b1 +b2)h

The bases are the parallel sides, 4.5 cm and 9 cm. The height is the perpendicular distance between them, 6 cm. Filling in these numbers, we have ...

A = (1/2)(4.5 +9)(6) = 40.5 . . . cm²
