A trapezium has two parallel sides of lengths 5cm and 9cm. If the area is 91cm\(^2\), find the distance between the parallel sides
Attached Figure / Diagram
A
13 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 parallel sides) * h
91 = \(\frac{1}{2}\) (5 + 9)h
cross multiply
91 = 7h
h = \(\frac{91}{7}\)
h = 13cm
