The lengths of the parallel sides of a trapezium are 10 cm and 20 cm. If the distance between these parallel lines is 5 cm, then what is the area of the trapezium?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 75 cm2.
Area of trapezium = 1/2 × (a + b) × h
a = 10 cm, b = 20 cm and h = 5 cm
Now, the area of the given trapezium = 1/2 × (10 + 20) × 5 = 15 × 5 = 75
Hence the required area of trapezium is 75 cm2.
