The length of the parallel sides of a trapezium are 19 cm and 13 cm and its area is 128 cm2. The distance between the parallel sides is
A. 9 cm

B. 7 cm

C. 8 cm

D. 12.5 cm

Answer :

Given


Length of parallel sides is 19 cm and 13 cm


Area of trapezium= 128 cm2


Let Height (h) =y cm


We know that area of trapezium is × (sum of parallel sides) × height


Therefore Area of trapezium is × (19 +13) × y =128 cm2.


× (19 +13) × y =128


× (32) × y =128


16 × y =128


y = = 8 cm


... Distance between the parallel lines is 8 cm.
