To find the perimeter just add the sides

5+5+6 = 16

To find the area, you need to use the following formula

[tex] area = \frac{1}{2}bh[/tex]
we know b but we need to find the height. We can find the heigh by using pythagorean theorem [tex]a^2 + b^2 = c^2[/tex]

height = [tex] a^2 + 3^2 = 5^2 [/tex]
             [tex] a^2 + 9 = 25 [/tex]
             [tex] a^2  = 25 - 9[/tex]
             [tex] a^2 = 16 [/tex] 
            [tex] a = \sqrt{16} = 4 [/tex] 
            h = height = 4

[tex] area = \frac{1}{2}\times 6\times 4 = 12cm^2[/tex]

Cost:

6.00 per cm^2 = 6.00 x 12 =  $72.00 dollars
check the picture below.

what's the cost? well is $6 per square foot, what area did you get? well, say you got A, so the cost is just  A * 6.
