3. Two parallel sides of a trapezium are 85 cm and 63 cm and its area is 2664 cm. Find its altitude​

Answer 1

Answer:

72cm.

Step-by-step explanation:

Area Of Trapezium = 1/2 * Sum of parallel sides * altitude.

Let Altitude be 'h'.

2664=1/2*(85+63)*h

2664=1/2*74*h

2664=37*h

h=2664/37 = 72cm.

Therefore, The Altitude of the trapezium = 72cm.
