A ration is basically a fraction. It can be written different ways i.e. 2/3 or 2:3. They are both the same thing. There are 5 girls out of 39 students... ratio= 5/39 or 5:39
Answer: 292 tiles
Step-by-step explanation:
To find the number of tiles needed , we need to know the area of the hexagonal tiles and also the area of the room.
<u>Area of hexagon</u>
The area of hexagon is given as :
Area = ![\frac{3\sqrt{3}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Csqrt%7B3%7D%7D%7B2%7D)
![a^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D)
Where a is the length of side.
Therefore:
A = ![\frac{3\sqrt{3}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Csqrt%7B3%7D%7D%7B2%7D)
![20^{2}](https://tex.z-dn.net/?f=20%5E%7B2%7D)
A =
X 400
A = (400 x 3 x
) / 2
A = ![\frac{2078.460969}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2078.460969%7D%7B2%7D)
A = 1039.23![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
Also to find the area of the room , we must first convert from m to cm
6.25 m = 6.25 x 100 cm
6.25m = 625 cm
4.85m = 485cm
Therefore: Area of the room = length x breadth
Area = 625 x 485
Area = 303125![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
Therefore , the number of tiles needed = area of the room / area of hexagon
Number of tiles = 303125/ 1039.23
N = 291.6823032
Therefore , the number of tiles needed ≈ 292
