Question:
Mark (✓) against the correct answer:
The parallel sides of a trapezium are 54 cm and 26 cm and the distance between them is 15 cm. The area of the trapezium is
(a) 702 cm2
(b) 810 cm2
(c) 405 cm2
(d) 600 cm2
Solution:
(d) $600 \mathrm{~cm}^{2}$
Area of the trapezium $=\left\{\frac{1}{2} \times(54+26) \times 15\right\} \mathrm{cm}^{2}$
$=\left(\frac{1}{2} \times 80 \times 15\right) \mathrm{cm}^{2}$
$=600 \mathrm{~cm}^{2}$
