Question

Find the area of the trapezium whose parallel sides are 25cm, 10cm, and the other sides are 14cm and 13cm?

Answer 1

Answer:

98cm2

Step-by-step explanation:

Find Area of triangle using herons formula

s= a+B+c/2= 21cm

After applying formula , area of triangle=

we get 42cm2

and now we have to find height of triangle.

7.5h= 42cm2

h= 5.6cm

and we know that area of trapezium= 1/2 * sum of parallel sides* distance between them

= 1/2*35*5.6= 98cm2
