    i guess so when I find the area for a square and two triangles I add it up or multiply it

    add adding is the same a "gluing" the pieces together to get the original shape.

    @phi so would I split the shape into one triangle and one rectangle and find the area , and when I find the area of both I add the two together and that is my area for the shape

    add the two blue lines in the picture. then count how many "boxes" tall and wide the "rectangle" is (it is actually a square) find its area. (base * height)

    *add the blue lines: I mean draw them in to form two triangles and a square

    a square and two triangles :/ why cant it be one triangle and one rectangle

    a rectangle has equal opposite sides. if we just do this (see fig2) the bottom figure is a trapezoid (the bottom is 7 wide and the top is 6 wide.. not a rectangle) if you know how to find the area of a trapezoid you can do that... but I was thinking it is easier to add a second blue line to the picture (see the first figure I posted) because you should know the formula for areas of rectangles (or square) and triangles

    @phi I will find the area of one triangle and one trapezoid and add it up then come back over and if don't mind if you can check that I did it correctly.

    ok. but you can check by dividing the trapezoid into a rectangle and triangle. That also will give the correct answer. If you get the same answer, you probably got it right.

    yes, 39 for the bottom trapezoid shape. how wide is the triangle (i.e. what is its base) ?
