What your going to want to do is take graph paper each square is five feet draw whatever shape your room is on it and take perimeter and area I cant write the reflection as I don't know what room you have drawn.
It is (2/3d)^3
Make sure the exponent is on the outside. This is because you are raising 2/3d. Not just D
ANSWER
672cm²
EXPLANATION
The area of a regular hexagon is given by the formula,

where a=14cm is the apothem and p=96cm is the perimeter of the regular hexagon.
We substitute the values into the formula,


Therefore the approximate area of the hexagon is 672cm²
Answer:
A) 6Gn + 12 (or 6n+12, if that’s what you meant)
B) 4p²+9p
C) 5r²+20r
Step-by-step explanation:
A. If you meant 6(n+2)...
Multiply 6 by n and also 6 by 2:
6n + 12
B. Multiply p by 4p and also p by 9
4p²+9p
C. Multiply 5r by r and also 5r by 4
5r²+20r
Hope this helped!
