Question

Hi,

 

I am trying to work through a)1)  and b)1) in the screen shot and can;t figure out what I get wrong here. Probably something pretty silly. But would like some help. Thanks.

In the applet below you can vary the size of the square using the purple X at the bottom-right corner of the square. The values of the ratios 2
and 4 are shown in the applet.
P/s = 4
A/s = 1.0
Perimeter: 4.0 cm
Area: 1 cn?
1.0 cm
Drag the purple X to adjust the size of the square.
a. Let's consider the relationship between P and s.
i. Write an expression that represents the measure P in units of s.
4s

1i. This measurement is
V constant. Therefore P and s are
Mv proportional.
b. Now, let's consider the relationship between A and s.
i. Write an expression that represents the measure A in units of s.
s^2
Preview
1i. This measurement is not
Vv constant. Therefore A and s are not
v proportional.
