In the figure below, if we considered the side length of the small squares of the lattice as 1 length unit,
find the length and width of the gray shape.
The longest side of the rectangle is 6 small squares long (from top to bottom). So, the length of the gray shape in 6 units.
The other side of the rectangle is 4 small squares long (from left to right). So, the width of the gray shape is 4 units.
