Question : The length of two parallel sides of a trapezium are 25 metres and 30 metres. If its height is 20 metres, then what is the area of the trapezium?
Option 1: 420 m2
Option 2: 350 m2
Option 3: 590 m2
Option 4: 550 m2
Correct Answer: 550 m 2
Solution :
Given: The length of two parallel sides of a trapezium is 25 metres and 30 metres and its height is 20 metres.
The area of the trapezium
= $\frac{1}{2}$ × The sum of parallel sides × Height
= $\frac{1}{2}\times (25+30) \times 20$
= $\frac{1}{2}\times 55 \times 20$
= $550$ m
