The length of room = 10 ft
the width = 14 ft
the height = 12 ft
there are 4 walls and the floor
one wall has area = 10*12=120 ft^2
4 walls has area = 4*120=480 ft^2
the floor has area = 10*14=140 ft^2
total area of walls and floor = 480+140= 620 ft^2
- so bc. we know that each tile is 1 foot long and 1 foot wide so what mean an area of 1 ft^2 and the total area equal 620 ft^2 so this mean that Jamie will need 620 tiles
I believe its C. Hope it helps lad
Answer:

A and D
Below and to the left both mean "less"

By dismantling
14 = 7 • 2
21 = 7 • 3
The least common multiple is
7 • 2 • 3 = 42
Hope this helps.
Step-by-step explanation:
The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :
![A=2\pi rh](https://tex.z-dn.net/?f=A%3D2%5Cpi%20rh)
or
![A=2\pi \times r\times h](https://tex.z-dn.net/?f=A%3D2%5Cpi%20%5Ctimes%20r%5Ctimes%20h)
We also know that, surface area = perimeter×height
So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.
