Answer:
ok i guess...
Step-by-step explanation:
1st part: 3x9x3
2nd part: 3x6x9
3rd part: add the product of those two steps
you have to break it down into two rectangular prisms and find the volume of each and then add
These triangles are not congruent. They only have 2 sides and one angle in common, and that is not a congruency theorem.
To find the perimeter it is 2 X Width + 2 X the length = 84
32+ 2 X the length = 84
2 X the length = 52
Therefore the length is 26cm
