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 , square 4 is , and square 6 is ,

what is the area of the sum of square 1 and 7?

2. Rhombus is inscribed in rectangle

such that lie on , respectively.

If

and is a simplified fraction which represent the area of ,

. . Where are ?

find

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

The area of a rhombus is the product of its diagonals: .

Therefore: .
