Question

the area of a Trapezium if 10500 metre square if one of the parallel sides is twice of the another parallel side and the distance between them is 70 cm find the parallel sides​

Answer 1

Answer:

$let \: the \: one \: parallel \: side \: be \: x \\ the \: another \: parallel \: side \: be \: 2x \\ area = \frac{1}{2} \times (a + b) \times h \\ 10500 \: {cm}^{2} = \frac{1}{2} \times (x + 2x) \times 70 \\ \frac{10500 \times 2}{70} = 3x \\ 300 = 3x \\ \frac{300}{3} = x \\ 100 = x \\ x = 100 \: cm \\ a = 1 \times 100 = 100 \: cm\\ b = 2 \times 100 = 200 \: cm$
