The answer is : 5 .
Step by step solution:
Let the width of the rectangle be x.
Width : x
Length : x + 2
x + x + 2 + x + x +2 = 24
4x + 4 = 24
4x = 24-4
4x = 20
x= 20/4
x=5

This curve is a parabola, the graph of a quadratic function. It has a kind of u-ish, v-ish shape. Right there at the bottom, where the curve appears to be making a u-turn, is the vertex. That point is at (3,-4).
Also, it is a low point of the curve, which makes it a minimum of this upward opening parabola. Sometimes this curve can be flipped upside down, in which case it would have maximum.
But this one has a minimum at (3,-4)
