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