Find the area of a trapezium whose parallel sides are 8.4 cm and 10.8 cm respectively, and the distance between the parallel sides is 7.5 cm.
Show answer & explanation
Correct answer: D
Explanation
Given:
Parallel sides = 8.4 cm, 10.8 cm
Distance between parallel sides = 7.5 cm
By formula:
Area of trapezoid = 1/2 × (a + b) × h
Area = 1/2 × (8.4 + 10.8) × 7.5
= 1/2 × 19.2 × 7.5
= 9.6 × 7.5
= 72 cm²
