They all have to have common denominators
The common denominator is 32
3/4= multiply by 8/8= 23/32
3/16= multiply by 2/2= 6/32
11/32. Is. 11/32
1/8 multiply by 4/4 =. 4/32
Smallest to greatest is 1/8. 3/16. 11/32. 3/4
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
The answer for number one is -3.938.
