A trapezium has two parallel sides of length 5cm and 9cm. If the area is 21cm2, find the distance between the parallel sides
A
3 cm
B
4 cm
C
6 cm
D
7 cm
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Area of Trapezium = 1/2(sum of parralel sides) * ht
21 = 1/2(5 + 9)h
42 = 14h
h = 42/14
h = 3cm
