and
The given rectangular coordinates are: (3,-3).
The two polar coordinates are:
Answer:
96 square tiles are needed
Step-by-step explanation:
To calculate this, the first thing we need to do is calculate the total area covered by the rectangular wall.
Mathematically, the area of the rectangle = 16 * 24 = 384 ft^2
The next thing we need to do is calculate the area of the square tiles = L^2 = 2^2 = 4 ft^2
the number of square tiles needed = Area of rectangular wall/Area of square tiles = 384/4 = 96
Lets say that y represents length and x width.
From the text we can write:
y=x/6 - 1
Perimeter we calculate:
P = 2*x + 2*y
now we use y equation from above and put it in perimeter equation:
P = 2*x + 2*(x/6 - 1)
P = 2*(7x/6 - 1)
P = 7x/3 - 2
