Question

Find the area of the figure.

10 cm
15 cm
20 cm
20 cm
The area of the figure is
square centimeters.

Answer 1

10 x 15 = 150

Area of trapezoid:

10 + 20 = 30

30 x 5 = 150

20 - 15 = 5

150 divided by 2 ( x 1/2) = 75

75 + 150 = 225 square cm

Formula of a trapezoid:

B1(base1) + B2(base2) x H (Height) x 1/2 (basically dividing by 2)
