Step-by-step explanation:
For this case, the first thing we must do is define variables:
x: number of pillowcases
y: number of sheets
We now write the system of equations:
2x + 5y = 40
x = 2y
Solving the system we have:
x = 8.9
y = 4.4
Answer:

The small squares are 1
We have 2 large squares = 2x^2
and 2 rectangles = 2x
2x^2+2x
