Question

Mathematics: A student uses square tiles measuring 1 inch on each side to find the area of the rectangle. I covered the top and bottom edges of the rectangle with 7 tiles each. I then covered the left and right edges with 3 tiles each. I added up all the tiles I used to get a total area of 20 square inches 7+7+3+3=20. Identify the two errors in the student s reasoning and describe how to correctly use square tiles to find the area of the rectangle. Give the correct area of the rectangle

The question is asking we convert from (x, y) coordinate to (r, theta) coordinates.
So (0, 4) to (r, theta)
x = 0 and y = 4.
r = âš (x^2 + y^2)
r = âš (0^2 + 4^2)
r = âš (0 + 16)
r = 4
Also theta = tan^(-1)(x/y) = tan^(-1) (0/4) = 0
So theta = 0
Hence the (r, theta) coordinate is (4, 0)
