Two parallelogram sides of a trapezium are 12 cm and 8 cm long and the distance between them is 6.5 cm. The area of the trapezium is

Options

A. `74 cm^(2)`
B. `32.5 cm^(2)`
C. `65 cm^(2)`
D. `80 cm^(2)`

Answer

C

Explanation

Area of the trapezium `=(1)/(2)xx` sum of parallel sides `xx` distance between them
`{(1)/(2)xx(12+8)xx(13)/(2)}cm^(2)=65 cm^(2)`.
