Final answer:
The area of a trapezoid with parallel sides measuring 12m and 18m and a height of 10m is 150 sq. meters.
Step-by-step explanation:
The area of a trapezoid is calculated using the formula:
Area = 1/2 * (sum of parallel sides) * height
Substituting the given values in this formula:
Area = 1/2 * (sum of 12 m and 18 m) * 10 m
= 1/2 * (30 m) * 10 m
= 150 sq. meters
So, the correct option is (a) 150 sq. meters.
