Question

The parallel sides of a trapezium are 20 cm and 16 cm. If the distance between the parallel sides is 12 cm, the area of the trapezium is:
(A) 206 cm²
(B) 216 cm²
(C) 226 cm²
(D) 236 cm²

Answer 1

1/2×36×12
18×12
216



ans. 216 cm ^2

Answer 2

Answer:

Option ( B ) is correct.

Step-by-step explanation:

**************************

If a , b are two parallel sides

of a trepezium and h is distance

between parallel sides , then

Area of the trapezium = [(a+b)h]/2

********************************

Here ,

Let a = 20cm ,

b = 16 cm,

h = 12 cm

A = [ ( 20 + 16 )×12 ]/2

= ( 36 × 6 )

= 216 cm²

Therefore ,

Area of the trapezium = 216 cm².
