Question

35. The parallel sides of a trapezium are 12 cm and 9 cm and the da
between them is 8 cm. Find the area of the trapezium.​

Answer 1

AnSwer -:



The area of trapezium is 84 cm^2


_______________________________

_______________________________

Formula of area of trapezium-:

“A = 1/2 x h (a+b)”

A = Area

H = height

(A+b) = sum of parallel sides

______________________________

Given ,

Height = Distance between them =

= 8 cm

Parallel sides are 12 cm and 9 cm

To find ,

Area of trapezium

______________________________


Formula of area of trapezium-:

“A = 1/2 x h (a+b)”

A = Area = ??

H = height = 8 cm

(A+b) = sum of parallel sides = (12 + 9)

Now ,

1/2 x 8 (12+9)

= 4 x (12+9)

= 4 x 21

=84 cm^2

Hence ,


The area of trapezium is 84 cm^2


_______________________________

Trapezium-: A trapezium is a 2d shape

and a type of quadrilateral, which has

only two parallel sides and the other two

sides are non-parallel.
