Homework Help: Area of Composite shapes.

  1. May 12, 2016 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    A = l x w
    A = hbb / 2
    3. The attempt at a solution
    To find the area of a rectangle you would use the formula "A = L x W". In this case A = 14 x 8 which is eual to 112, Now all i need is the area of the triangle and then i add them together and that will be the area of the whole figure.

    So i know we have the height of the triangle is 5
    Also the part i colored yellow is 8 m long.

    So my question is how can i find the length of 1 of the sides of the triangle.

    Why would you need to find that?

    I need to find the area of that triangle, that way i can find the whole area of that composite shape.

    for area of that triangle you already have the base ( 8m) and height (5m), so you don't need to calculate other sides, you can directly calculate the area.
