Rational number I believe
That is an isosceles right triangle. (Also known as a 45 45 90 triangle).
5/35 so 1/7 as a decimal this is .143. This is because it says D OR F which means add them and divide by 35. So your answer is 0.143
Add up the sides and you will get your perimeter
I would say A because you would have to convert 3/2 to a mixed number which would be 1 1/2
