Answer:
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.
