Question

Find the area of the trapezium, if sum of the parallel sides and height are 12cm
and 5cm respectively
1) 50 sq. units 2) 30cm
3) 36.5cm
4) 60cm
​

Answer 1

Answer:

60 cm

Step-by-step explanation:

formula for area of trapezium=1/2×height×(a+b)

area of trapezium= 1/2×12×(5+5)

=1/2×12×10. (2×6=12) cancel 2 and 12 as 6

so = 6×10

=60

Answer 2

Answer :-

Area of Trapezium is 30 cm² .

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.
