Answer:
the length of the room = 25 feet
Step-by-step explanation:
Area =W*L
Area = 17*L =425
Divide all by 17
L=25
17*25=425
The answer is $44.10. You times 42 by 0.05 and then add that answer to 42 and you get 44.10
Answer:
-200
Step-by-step explanation:
1-3=-2
101-1=100
-2×100=-200
3/40 is a fraction itself.
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 =
Where a is the length of side.
Therefore:
A =
A = X 400
A = (400 x 3 x ) / 2
A =
A = 1039.23
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
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
