What is the area of a trapezium whose parallel sides are 20 cm and 10 cm and height is 8 cm?
Show answer & explanation
Correct answer: A
Explanation
Parallel sides = 20 cm, 10 cm; Height = 8 cm
According to the formula: Area = (1/2) × (a + b) × h
= (1/2) × (20 + 10) × 8
= (1/2) × 30 × 8
= 15 × 8 = 120 cm²
