The lengths of a pair of parallel sides of a trapezium are 20 cm and 25 cm, respectively, and the perpendicular distance between these two sides is 14 cm. What is the area (in cm2 ) of the trapezium?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 315.
Given:
Length of parallel sides = 20 cm and 25 cm
Height = 14 cm
Formula Used:
Area of trapezium = ½ × (a + b) × h
where a and b are parallel sides
h is height.
Explanation:
According to the given question,
Area of trapezium = ½ × (20 + 25) × 14
⇒ Area of trapezium = 45 × 7
⇒ Area of trapezium = 315
Hence the required answer is 315 cm2.
