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
1.
C= 3.14 * 9
C= 28.26
The circumference is 28.3 cm......
2.
C=3.14 * (2*13)
C=3.14 * 26
C= 29.14
The circumference is 19.1 cm....
