Question

The area of a trapezium is 220 square meter and its parallel sides measure 20 meter and 25 meter. Find the height of the trapezium.



​

Answer 1

Answer:

height is 9.78 m.

Step-by-step explanation:

$area = \frac{1}{2} (x + y)(h) \\ \\ 220 = \frac{1}{2} (x + y)(h) \\ \\ h = \frac{220 \times 2}{x + y} \\ \\ h = \frac{220 \times 2}{20 + 25} \\ \\ h = \frac{220 \times 2}{45} \\ \\ h = 9.78 \: m.$
