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! =)

Answer:
8.921513269...g/cm
Step-by-step explanation:
the density has this formula: D= m/V
so to solve the V, which refers to volume, you do: 8.4×5.5×4.6= 212.52, and the m, which refers to mass, you already have it. So the last thing to do is:
D= 1896g/212.52= 8.921513269...g/cm
I hope I've been helpful... good luck...!!!
