Question 116

The length of two parallel sides of a trapezium are 15 cm and 20 cm If its area is 175 sq.cm, then its height is :

Sum of the two parallel sides of the trapezium = $$15+20=35$$ cm

Let its height = $$h$$ cm

=> Area of trapezium = $$\frac{1}{2}\times$$ (sum of parallel sides) $$\times$$ height

=> $$\frac{1}{2}\times35\times h=175$$

=> $$h=\frac{175}{35}\times2$$

=> $$h=5\times2=10$$ cm

=> Ans - (A)
