A trapezium has two parallel sides of lengths 5cm and 9cm. If the area is 91cm\(^2\), find the distance between the parallel sides
A.
13 cm
B.
4 cm
C.
6 cm
D.
7 cm
Correct answer is A
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
