# If its area is 175 sq. cm, then its height is:

The length of two parallel sides of a trapezium are 15 cm and 20 cm. If its area is 175 sq. cm, then its height is:

- 10 cm
- 25 cm
- 20 cm
- 15 cm

**Answer: (1) 10 cm **

**Explanation:-**

**Given-**

The length of two parallel sides of a trapezium = 15 cm and 20 cm

The area of the same trapezium = 175 sq. cm

**Formula-The area of the trapezium = height x the sum of parallel sides **

Then, height x (15 + 20)/2 = 175

height = 175 x 2/35

= 350/35

= 10

Then, the height of the trapezium is 10 cm.

Hence, the answer is (1) 10 cm.
