Find the area of a trapezoid with bases 12 cm and 18cm and height 10cm

150 cm^2 (squared)

Step-by-step explanation:

Area of a trapezoid is A=1/2(Base1 + Base2) x Height or

A= ((Base1 + Base2) / 2) x height

((12+18)/2) x 10

((30)/2) x 10

(15) x 10

150 cm^2

So in this case it would be 12+18 which is 30

((12+18)/2) x 10

((30)/2) x 10

Then 30 divided by 2 is 15.

(15) x 10

15 times 10(height) is 150.

Then add the units (cm) and squared since the area.

10

step-by-step explanation:

7+3=10

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
