A rectangular floor covered without overlaps or gaps by 7 identical tiles, each of the length l and with w. If the w=12 ft, what is the total area of the floor?
Answer:
The slope is 2/3
Step-by-step explanation:
To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

"d" represents the distance and coordinates are expressed as follows: (x, y)
Let's go to the calculations.

The answer is 12,6 u.c.
