    Post working with squares.

    I need help on these. Thanks very much.

    1. Assume there are seven squares in a surface such that square 1, 3, 5, 7 are placed on the flat form while square 2, 4, and 6 are placed on an inclined position. If the area of square 2 is a, square 4 is b, and square 6 is c, what is the area of the sum of square 1 and 7?

    Hello, mathisgood!

    We need some clarification . . .


    1. Assume there are seven squares in a surface such that:
    squares 1, 3, 5, 7 are placed on the flat form .
    What does this mean?
    while squares 2, 4, and 6 are placed on an inclined position. .
    ... and this?

    If the area of square 2 is a, square 4 is b, and square 6 is c,
    what is the area of the sum of square 1 and 7?


    2. Rhombus MNOP is inscribed in rectangle WXYZ
    such that M, N, O, P lie on WX, XY, YZ, ZW , respectively.

    If MX\,=\,15,\;XN\,=\,20,\;MO\,=\,30,\;NP\,=\,40,

    and \tfrac{a}{b} is a simplified fraction which represent the area of ABCD,
    . .
    Where are {\color{blue}A,B,C,D} ?

    find a+b.

    If you meant the area of rhombus MNOP, then T.M.I. (too much information).

    The area of a rhombus is the product of its diagonals: . 30\cdot40\:=\:1200

    Therefore: . \frac{a}{b} \:=\:\frac{1200}{1} \quad\Rightarrow\quad a + b \;=\;1201
