Answer:
The second answer is correct 5/4.
Explanation:
Lets give some values for the base and the height.
The perimeter of a triangle =b+h
Lets say b=1 and h=2
Perimeter 1+2=3
b=1*(5/4)=1.25
h=2*(5/4)=2.5
1.25+2.5=3.75
3.75/3=1.25
A 4/5=0.8 so is wrong
B 5/4=1.25 so is right
C 25/16=1.5625 so is wrong
D 16/25=0.64 so is wrong
