a+b+c/2
15+14+13/2
42/2=21
Underroot[(s-a)(s-b)(s-c)]
underroot [21(21-15)(21-14)(21-13)]
Underroot [21(6)(7)(8)]
Now factories 21,6,7 and 8
It will be
Underroot (7,3)(3,2)(7)(2,2,2)
Now, 7(3)(2)(2)=84
When u will multiply 7,3,2 and 2 u will get 84..
Now, Area of triangle=1/2(b)(h)
So 84=1/2(15)(h)
168/15=h
h=11.2
Then, Area of trapezium=1/2(b1+b2)h
1/2(25+10)11.2
1/2(35)11.2
Now divide 2 and 35 we will get 17.5
Now multiply 17.5 and 11.2 and the final answer will be 196...
