Question

The lengths of the parallel sides of a trapezium are 30 cm and 10 cm, and the distance between them is 20 cm. What is its area?

• A. $280c{m}^2$
• B. $360c{m}^2$
• C. $400c{m}^2$
• D. $480c{m}^2$

Answer 1

The correct option is C $400c{m}^2$

Area of the trapezium $=\frac{1}{2}(a+b)d$
$=\frac{1}{2}\times (30+10)\times 20=400c{m}^2$
