All 4 sides of a square are of the same length.

The formula for the area of a square is s*s = area where s is the length of one side of the square.


s^2 = 81

s = 9 or -9

-9 does not apply here but 9 does.

 Each side of the square deck is 9 feet long.

Describe the difference between parallel and perpendicular lines, their slopes and graphs
Aloiza [94]

Parallel lines have the same slopes (but different y intercepts). Parallel lines never cross. Parallel lines are the same distance from each other no matter where you are on either line. Think of it like a pair of perfectly straight railroad tracks.

-------------------------------------------------------------------------------------

Perpendicular lines cross at one point. The two lines form a 90 degree angle. The two slopes multiply to -1, which is another way of saying that the slopes are negative reciprocals of one another. For example, a line with a slope of 2/3 and another line with a slope of -3/2 has these two values multiply to -1; therefore showing they are perpendicular lines.
