Question

The length of parallel sides of a trapezium are in the ratio 3:2 and the distance between them is 10 cm. If the area of a trapeziyum is 325 cm find the length of the parallel sides

Answer 1

$325 = \frac{1}{2} \times (3x + 2x) \times 10 \\ 325 = 5x \times 5 \\ \frac{325}{25} = x \\ x = 13 \\ side = 39 \: and \: 26$
