Question

Find the area of the trapezium,
if sum of the parallel sides height are 12cm and 5cm respectively (please give the full solution)
​

Answer 1

Given: Length of parallel sides are 9cm and 5cm

Height =8cm

Area of trapezium=

1

× Height ×(Sum of parallel sides)

=

same question hai but digits change hai don't worry.

Answer 2

Given :

Sum of the parallel sides and height are 12cm and 5cm respectively

To Find :

Area of Trapezium.

Solution :

As Given that Sum of the parallel sides and height are 12cm and 5cm respectively So ,

Using Formula :

$\tt\boxed{Area\:of\:Trapezium=\dfrac{1}{2}\times{(Sum\:of\:parallel\:sides)}\times{h}}$

Putting Values :

$\longmapsto\tt{A=\dfrac{1}{2}\times{(12)}\times{5}}$

$\longmapsto\tt{A=\cancel\dfrac{60}{2}}$

$\longmapsto\tt\bf{A=30}$

Therefore :

$\longmapsto\tt{Area\:of\:trapezium}$

$\longmapsto\tt\bf{30\:cm^2}$

So ,

Area of Trapezium is 30 cm² .

Hence,

Option (B) 30 cm² is correct.
