Solved Example on Trapezoid
Ques: A trapezoidal flowerbed has parallel sides of lengths 12 m and 6 m. Find the area of the flowerbed, if its height is 8 m.
Choices:
A. 76 m^{2}B. 72 m^{2}
C. 68 m^{2}
D. 74 m^{2}
Correct Answer: B
Solution:

Step 1: Flowerbed is in the form of a trapezium
Step 2: Area of the trapezoid ADEF = Area of the triangle ABF + Area of the triangle CDE + Area of the rectangle BCEF
Step 3: Area of the triangle = (base x height) [Formula.]
Step 4: Area of the triangle ABF = (3 x 8) = 12 m^{2} [Substitute and simplify.]
Step 5: Area of the triangle CED = (3 x 8) = 12 m^{2 } [Substitute and simplify.]
Step 6: Area of the rectangle BCEF = 6 x 8 = 48 m^{2 } [Area of the rectangle = length x width.]
Step 7: So, the area of the flowerbed = 48 + 12 + 12 = 72 m^{2}
