Answer:

Step-by-step explanation:

I'm assuming you only need the first triangle. You didn't specify. If you need it after I answer the first one I'll be happy to help though.
To find the area of a triangle you go b(h)/2=a
6cm(3cm)/2
18/2
Area=9
To find the perimeter you add all of the sides together.
4+4+6=P
4+10=P
14= Perimeter

Answer:
7 is the answer you're looking for
The answer is 16in.
Let the radius and height of cylinder A be Ra and Hb respectively and the radius and height of cylinder B be Rb and Hb respectively.
Using similar shapes:
Ra/Ha= Rb/Hb
5.6/Ha=1.4/4
Ha=(4×5.6)/1.4
Ha=22.4/1.4
Ha=16in
