If four coordinates are given then:-
- Find length of the sides using distance formula

- Now break down into two triangles .
- Use herons formula and find areas of the triangles .add them and get the area
Answer:
x^4 + 5x^3 - 12x^2 + 5x + 1
Answer:
159cm
Step-by-step explanation:
Sum of all sides of triangles is 180
so, 15+6=21
then 180-21=159
Log(2x*12)=3
10^3=2x*12
1000=24x
1000/24=x
x=41.667
Answer:
