A trapezoid has bases that measure 9 cm and 5 cm. The height of the figure is 4 cm. What is the area of the trapezoid?
zzz [600]

Answer:

28 square centimeters

The area of a trapezoid (formula):

(a + b) ÷ 2 x h

Where a & b are the bases, and h is height.

Use formula with given measurements:

(9 + 5) ÷ 2 x 4 = 28

(centimeters in this case)

Therefore the area if the trapezoid is 28 cm^2

I really hope this helps!
