A rectangular floor of area 21.6 m2 is going to be tiled. Each tile is rectangular, and has an area of 576 cm2. An exact number
of tiles can be put into the space. How many tiles will be needed?

Answer:
375
Step-by-step explanation:
You want to find a number n which fulfills
21.6 m2 = n * 576 cm2.
Be careful! The units are different on the left and right side of the equation.
If we change to m2 on the right side, than that means we have to divide by 10.000 becaus 1 m2 is equivalent to 10000 cm2.
(1 m2 = 1 m * 1 m = 100 cm * 100 cm = 10000 cm2)
That gives us
21.6 m2 = n * 0.0576 m2
Now divide both sides of the equation by 0.0576 m2 and we get
= n
375 = n
Answer:
Area of floor = 21.6m2
area of tile = 576cm2=0.0576m2
now,
number of tiles = 21.6/0.0576
= 375

Answer:
So there are 8 five-point problems and 30 two-point problems
formula for the slope of a line, problem solving by solving simpler parts first, and cartesian plane for graphing.
75=14y+5
or, -14y=5-75
or, -14y = -70
or, y = -70/-14 = 5
The answer is 5.
