Question

the area of a Trapezium is 220 square metre and its parallel sides measure 20 and 25 m find the height of the trapezium

Answer 1

We know ,
Area of trapezium=1/2*sum of parallel sides *height
So answer is h=9.77

Here is your answer

Let height of the trapezium is x m

AREA = 220 Sq.m

As we know the formula
Area of Trapezium = 1/2(Sum of parallel side)(Distance between them)

$220 = \frac{1}{2} \times (20 + 25) \times x \\ \\ 220 \times 2 = 45x \\ \\ 45x = 440 \\ \\ x = \frac{440}{45} \\ \\ x = 9.77m$

Therefore Height of the trapezium is 9.77 m
