Jia is tiling a floor. The floor is a square with side

NNADVOKAT [17]

Answer:

36 tiles

Step-by-step explanation:

First, find area of the square floor knowing the formula as;

Area= $s^{2}$

where s= side of a square.

If one side of the floor is 12 feet, then Area= $12^{2} = 144ft^{2}$

Next, find the area of each tile using the same formula and given s=2 feet;

Area(tile) = $2^{2} = 4ft^{2}$

To find the number of tiles needed to cover entire floor, divide area of the floor by area of one tile; 144 / 4 = 36 tiles

Find the value of c. 64 32 5c+2 C

Dmitry [639]

Answer:

c = 6

Step-by-step explanation:

(I'm going to call the unidentified inner angle Henry, 'kay?)

First, we need to find Henry.

64 + Henry = 180

(64 - 64) + Henry = (180 - 64)

Henry = 116

Now to c.

Henry + 32 + 5c + 2 = 180

(116 + 32 + 2) + 5c = 180

(150 - 150) + 5c = (180 - 150)

5c/5 = 30/5

c = 6
