Question: One side of a parallelogram is 18 cm and its distance from the opposite side is 8 cm. The area of the paralleogaram is :
A
`144 cm^2`

B
`72 cm^2`

C
`48 cm^2`

D
`100 cm^2`

Question: A parallelogram has sides 30 m and 14 m and one of its diagonal is 40 m long. Then, its area is :
A
`336 m^2`

B
`168 m^2`

C
`480 m^2`

D
`372 m^2`

Note: Let ABCD be a 11 gm in which AB = 30 m BC = 14 m & AC = 40 m. Clearly, area of 11 gm ABCD = 2 (area of ABC). Let a = 30, b = 14 & c = 42. Then, `s = 1/2 (a + b + c) = 42` :. Area of

Question: The two parallel sides of a trapezium are 1.5 m and 2.5 m respectively. If the perpendicular distance between them is 6.5 metres, the area of the trapezium is :
A
`26 m^2`

B
`13 m^2`

C
`20 m^2`

D
`10 m^2`

Note: Area of trap` = 1/2 (Sum of parallel sides xx distance between them)` `= [1/2 (1.5 + 2.5) xx 6.5] m^2` `= 13 m^2`.

Question: The parallel sides of a trapezium are in the ratio of 3 : 5 and the perpendicular distance between them is 12 cm. If the area of the trapezium is 384 sq. cm, them the smaller of the parallel sides is :
A
16 cm

B
24 cm

C
