Mathematics

Westkost [7]2 years ago

answer

7.24

explanation

40% of 6000 = 2400

6000-2400=3600

labour's cost = 2400

material cost = 3600

15% of 2400 = 360

2400 + 360 = 2760

20% of 3600 = 720

3600 - 720 = 2880

2760 + 2880 = 5560

6000 : 5560 = 92.76

gap = 100.00 - 92.76

= 7.24

How do u guys solved this?
TEA [102]

Answer:

3 boxes

Step-by-step explanation:

First, we need to find the area of the whole square, so we can find out how much to subtract from. We can easily do this by multiplying 16 by 16, since it is a square.

16*16=256 square feet.

Now, we just need to find the area of the circular rug, and subtract it from 256 to find the area not covered by the rug that needs to be tiled. Since the sides of the rug touch each side of the floor, than the diameter will be the same as the side length of the square. Thus, the diameter is 16.

Now we can use the equation <em>A=pir^2 </em>or <em>Area=pi*radius squared</em> to find the area of the circle. The radius is halve of the diameter, so divide 16 by 2 to get the radius, or 8. Now all we have to do is square 8 and multiply it by 3.14.

8^2=64

Now multiply.

64*3.14=200.96.

The area of the circle is 200.96, so subtract 200.96 from 256.

256-200.96=55.04.

So they will need 3 boxes to cover the area left.

Hope this helps!
