Answer:

Perimeter= 12 feet Area= 6 feet (squared)

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! =)
