Answer 2

Explanation:

Given :-

Area of a trapezium is 320 cm² and 16 cm and 48 cm are lengths of two parallel sides

To Find :-

Distance between them

Solution :-

Let the height be h

Area = 1/2 × (a + b) × h

320 = 1/2 × (48 + 16) × h

320 × 2 = 64 × h

640 = 64h

640/64 = h

10 = h

Hence

Distance between them is 10 cm.
