The length of the parallel sides of a trapezium are 5cm and 7cm. If its area is 120cm\(^2\), find the perpendicular distance between the parallel sides
5.0cm
6.9cm
10.0cm
20.0cm
स्पष्टीकरण
Area of trapezium = \(\frac{1}{2} (a + b)h\)
\(120 = \frac{1}{2} (5 + 7) \times h\)
\(120 = 6h\)
\(h = 20 cm\)
