Answer 1

Answer:

Solution :-

Area of trapezium = 1/2 × Sum of the two parallel sides × Perpendicular distance (Height)

Let the length of the other parallel side of the given trapezium be x cm

⇒ 850 = 1/2 × (64 + x) × 17

⇒ 850 × 2 = 17 × (64 + x)

⇒ 1700 = 1088 + 17x

⇒ 17x = 1700 - 1088

⇒ 17x = 612

⇒ x = 612/17

⇒ x = 36

Hence, the length of the parallel side is 36 cm
