Answer:
40 meters
Step-by-step explanation:
The ratio of width to length is 2/3, so the width of the floor is ...
width = (2/3)(12 m) = 8 m
The perimeter is found from ...
P = 2(L +W)
P = 2(12 m +8 m) = 40 m
The perimeter of the floor is 40 m.
_____
<em>Additional comment</em>
As above, the perimeter is twice the sum of length and width. In terms of ratio units, that is p = 2(3 +2) = 10. The length is 3 ratio units, so the perimeter is 10/3 times the length. (10/3)(12 m) = 40 m.

Answer:
Number of vertices are <em>34</em>.
Step-by-step explanation:
The relation between the number of vertices, number of edges and number of faces was given by <em>Euler's formula</em>, which is as under:
Where is the number of faces in the polyhedron.
is the number of vertices in the polyhedron and
is the number of edges in the polyhedron.
Let us try to apply this formula in a cube. We know that number of vertices are 8, number of edges are 12 and number of faces are 6.
6 + 8 - 12
Hence, the formula is applicable.
Applying Euler's formula in the given question.
F = 14
E = 46
V = ?
Using Euler's Formula:
Hence, number of vertices are <em>34</em>.
