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.
