Not at all. All quadrilaterals can be skewed into parallelograms and so are not strong. They need to have a diagonal brace - effectively making two triangles.

you need to be strong
The demand for skilled construction workers is strong and likely to increase. According to the Construction Sector Council, the average construction worker is in their early 40s.
It is strong and lightweight.
In a 4 by 4 grid, there are 16 squares (1x1 squares), 9 rectangles that are 2x1, 6 rectangles that are 3x1, 4 rectangles that are 2x2, and 1 rectangle that is 4x4. Therefore, in total, there are 16 squares and 20 rectangles in a 4 by 4 grid.
It is NOT as case of 'Some'. It is ALL rectangles are parallelograms.
All squares are rectangles also, but not all rectangles are squares, only equilateral rectangles are considered square.
All rectangles are quadrilaterals. A quadrilateral has 4 sides; all rectangles have 4 sides; thus all rectangles are quadrilaterals.
