Question

PLEASE help me...Suck at math. find the following using the given triangle.

Answer 1

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.

Answer 2

To find the perimeter just add the sides

5+5+6 = 16

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

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

height = $a^2 + 3^2 = 5^2$
             $a^2 + 9 = 25$
             $a^2 = 25 - 9$
             $a^2 = 16$ 
            $a = \sqrt{16} = 4$ 
            h = height = 4

$area = \frac{1}{2}\times 6\times 4 = 12cm^2$

Cost:

6.00 per cm^2 = 6.00 x 12 =  $72.00 dollars
