    I understand perimeter but i just don't get the concept of finding the perimeter with the area and height

    FFirst you have to find the length of the side

    Pythagorean Theorem In any right triangle, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares whose sides are the two legs. Translated meaning is the long side squared equals the sum of the two other sides squared. use that to find the length of the side

    i understand that so would you do 30 squared + 12 mm= Hyp

    now that you have all the sides of the triangle (30,12,32.31099) use this formula (a+b+c= the perimeter

    You know the area. 1/2*b*h.. you know the height.. find the base.. once you know the base and height.. find the hypotenuse using pyth theorem.. And base, height, hyp.. that gives you the perimeter.

    All you have to do is multiply the area by 2 and divide it by the height of the triangle. This should give you the base.
