Yani walked the perimeter of a square patio that was 5.3 meters on each side. What is the distance that Yani walked?

21.2 meters

Step-by-step explanation:

The perimeter of a square = 4s

Where, s = side length of the square

Given that, side length, s = 5.3 meters

Perimeter = (4 * 5.3) = 21.2 meters.

Hence, distance Yani walked = perimeter of square patio = 21.2 meters

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
