The length of two parallel sides of a trapezium are 15 metre and 20 metre. If its height is 22 metre, then what is the area of the trapezium?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 385 metre2
Given:
Length of two parallel sides of a trapezium are 15 metre and 20 metre
Height is 22 metre
Formula used:
Area of trapezium = (1/2) × (a + b) × h
Where a and b are parallel sides and h is the height of trapezium
Calculations:
According to the question;
⇒ Area of trapezium = (1/2) × (15 + 20) × 22
⇒ 35 × 11 = 385 metre2
