A pond is in the shape of a trapezium. A bridge is to be constructed such that the bridge is perpendicular to the parallel sides. It is given that the area of a pond is 1080 m2 and the lengths of its parallel sides are 55.6 m and 34.4 m. Find the length of the bridge.
24 m
Area of trapezium = h(a+b)2 sq. units
Let the length of bridge be x
⇒ 12 × (55.6 + 34.4) × x = 1080m2
⇒ 12 × 90 × x = 1080m2
⇒ 108045 = x
⇒ x= 24 m
