    So for the shaded area we need to divide it into three sections two rectangles and a triangle to determine the total area

    The first rectangle we will do is the bottom A=lw Where A is area, l is length and w is width So A =8x2=?

    so i just multiply 8*2

    Yes that will give you the area of the first rectangle so one of three parts of the shaded section

    Yep so that's the first one so let's do the second rectangle or the middle sort of section

    So the second rectangle A=lw =(1)(8+2) We get the 8+2 because the side length is split into two parts so we just have to put them together

    so just add 8 plus 2

    Yep for that's all you have to do for that one cause the side length is 1

    So the last part of the shaded area is the triangle and yes 10 is right for that second rectangle

    A=bh/2 Where b is the base (8-2-2-1)=3 and h is the height 8+2=10 So A= (3)(10)/2

    The area of a triangle is represented by Area= base times height all divided by two A=bh/2 A=(3)(10)/2 A=30/2 A=15

    There are three parts to the shaded area so to find the total area of the shaded section so the total area=16+10+15

    oh ok so just add all thre of those

    Yes if you add those three together you will get the total area of the shaded area

    which is 41

    what about the non shaded area

    So to find the area of the no shaded area first we need to find the total area of the square A=lw A=(8)(16)

    so 128

  31. taramgrant0543664
    • one year ago

    Yes so that's the area of both the non shaded area and the shaded area so you just need to subtract the shaded area from that total area to find the non shaded area So 128-41= the nonshaded area

    Yes that 87 would be the area for the non shaded section
