1.	In a trapezium if the sum of the parallel sides is 10 m and the area is 140 sq.m, then the height is (i) 7 cm (ii) 40 cm (iii) 14 cm (iv) 28 cm
Answer» (iv) 28 cm Area = \(\frac{1}{2}\) x h x (a + b) = 140 = \(\frac{1}{2}\) x h x 10 ⇒ h = 28

In a trapezium if the sum of the parallel sides is 10 m and the area is 140 sq.m, then the height is (i) 7 cm (ii) 40 cm (iii) 14 cm (iv) 28 cm

Answer»

(iv) 28 cm

Area = \(\frac{1}{2}\) x h x (a + b) = 140 = \(\frac{1}{2}\) x h x 10

⇒ h = 28
