I'm so confused on how to even start my homework. i'm so confused and this is due soon, so me as soon as possible. i would really appreciate it. also, tomorrow i have a test on this which is worth 15% of my !

Well i ll give u some tips
1-u should know the formulas for calculating different objects areas
2-find the length of their sides or diagonals(which are needed on the formula)
3-calculate the area

for example the triangle on the picture
1-s=leg1*leg2/2
2-the length of:leg1=10-3=7,,leg2=7-1=6
3-s=7*6/2=21

The points are -8 and 8
