Question 936078
The perimeter of a square porch is 3 more than the area. Find the length of a side, it's area, and it's perimeter.
-------------
Perimeter = 4s where s is an edge of the square
Area = s^2
-----
Equation:
4s = s^2 + 3
-------------------
s^2 - 4s + 3 = 0
(s-3)(s-1) = 0
s = 1 or s = 3
-----
If s = 1, area = 1 ; perimeter = 4
---
If s = 3, area = 9 ; perimeter = 12
