Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.
So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.

Step-by-step explanation:
In order to calculate the surface area you take into account the five faces of a triangular prism. You calculate the area of two rectangle triangle, and three rectangles. This can be summarized in the following formula:
h: height
w: width
s: slope
l: length
1. By replacing you obtain:
