Your answer would be -0.6 cm.
just take -2.4/4
= -0.6
It is -2.4 because his height decreased each year.

So it states that the area of the rectangle is 56 cm, so all of it.
Given: 56 cm of rectangle
Unknown: find x
Length: 2 + x or x + 2
Width: 2x-5
Area = l * w
(x+2)(2x-5)
set x equal to 0
x+2=0 --> x=-2 2x-5=0 --> 2x=5 --> x = 5/2
so the answer we got was x=-2,5/2
we know that x cannot be negative because you can't measure with negative numbers, therefore, 5/2 is your answer
X² = 16
the way to isolate your x variable is to square root both sides
√x² = √16
x = <span>± 4
so your answers are 4 and -4</span>
