Step-by-step explanation:
Follow the slashed line drawn in the figure
You will get two triangles
Now use the heron's formula= √s(s-a)(s-b)(s-c)
where s is semi perimeter= (a+b+c)/2
a, b, c are the sides of the triangle
Then add the areas of two ∆s
Answer:
this is the ans and b part will be done in the same way
