Question

A right triangle has sides of length 3 feet, 4 feet, and 5 feet what is its perimeter? What is its area?

Answer 1

Answer:

Perimeter= 12 feet   Area= 6 feet (squared)

Step-by-step explanation:

Perimeter= Adding all the sides together, that means it is 3+4+5= 12 feet

Area= Hight times base divided by 2. Because hight times base is area of a rectangle, and a right triangle (and all other triangles) is half of it. Because it is a right triangle, its hight must be 3 or 4, and base also 3 or 4. But no the same number twice, so 3*4=12, 12/2=6 feet (squared).

I hope that helped! =)
