Question

The area of a trapezium shaped field is 480 m2 the distance between two parallel sides is 15m and one of the parallel side is 20m find the other parallel side

Answer 1

Area of trapezium = h (a+b) / 2

$480 = \frac{15(20 + b)}{2}$
$480 \times 2 = 300 + 15b$
$960 - 300 = 15b$
$660 = 15b$
$\frac{660}{15} = b$
$44 = b \: \: \: or \: \: \: b = 44$
Therefore the length of nother parallel side is = 44
