# Math Help - Wire of Length x

1. ## Wire of Length x

A wire of length x is bent into the shape of a square.

(a) Express the perimeter of the square as a function of x.

(b) Express the area of the square as a function of x.

2. 1. P = x
2. S = (x/4)^2

3. ## ok but...

Perimeter of the square $P(x)=\frac{1}{4}x+\frac{1}{4}x+\frac{1}{4}x+\frac{ 1}{4}x=\frac{4}{4}x=x$

Area of the square would be $A(x)=\left(\frac{1}{4}x\right)^2=\frac{1}{16}x^2$
