Answer:
So there are two possibilities:
x = 3, y = 10
x = 10, y = 3
Explanation:
Make two equations:
Length = x
Width = y
xy = 30
2x + 2y = 26
You can simplify the second equation to:
x + y = 13
x = 13 - y
(13 - y) * y = 30
13y - y^2 = 30
y^2 - 13y + 30 = 0
Factor:
(y - 3)(y - 10) = 0
y = 3, y = 10
So there are two possibilities:
x = 3, y = 10
x = 10, y = 3
