Question : The ratio of the length of parallel sides of a trapezium is 3 : 2. The shortest distance between them is 15 cm. If the area of the trapezium is 450 cm2, the sum of the length of parallel sides is:
Option 1: 15 cm
Option 2: 36 cm
Option 3: 42 cm
Option 4: 60 cm
Correct Answer: 60 cm
Solution :
Let the parallel sides of the trapezium be
We know,
Area of trapezium =
⇒ 450 =
Hence, the correct answer is 60 cm.
