I don’t know if this is correct just saying
Problem 1
a = 1/2 bh
a = 1/2 x 5.3 x 6.1
a = 1/2 x 32.33
Answer for area is 16.165
6.1 + 6.1 + 6.1 = 18.3 perimeter
Type: equilateral
I have no clue for number 2 sorry
Number 3
a = 1/2 b h
a = 1/2 9.7 x 5.6
a = 1/2 54.32
a = 27.16
6.22 + 8.95 + 9.7 = 24.87 perimeter
Type: scalene
I think this is correct and sorry again I don’t know number 2
