Calculate the length of the shorter of the two sides of a rectangle which has an area of 31.20 m2 and a perimeter of 23.80 m.
----------------
Equations:
L + W = 23.8/2 = 11.9
LW = 31.2
----------------------------
Substitute for "L" and solve for "W":
(11.9-W)W = 31.2
-----
W^2 -11.9W + 31.2
-----
Solve for "W":
W = 3.9 or W = 8
----
Shorter side = 3.9 meters
