Question

The area of a trapezium is 850 sq.cm. One of the parallel sides is 64 cm and the perpendicular distance between the parallel sides is 17 cm. Find the length of other parallel side.

Answer 1

X be 36 hope it will hlp u.....

Answer 2

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
