Question

The parallel sides of a trapezium are 35 cm and 21 cm, the perpendicular distance between the parallel sides is 23 cm. Find the area of the trapezium.

• A. 144 $c{m}^2$
• B. 644 $c{m}^2$
• C. 244 $c{m}^2$
• D. 344 $c{m}^2$

Answer 1

The correct option is B 644 $c{m}^2$

Area of trapezium
$=h\times \frac{(a+b)}{2}squnits,$
where a and b are the lengths of parallel sides and h is the perpendicular distance between the parallel sides.

$\therefore Area=\frac{1}{2}\times (35+21)\times 23=644c{m}^2$
