Answer:
$760
Step-by-step explanation:
950 x 0.8 = 760
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
