**After Reducing Each Side by 4 cm, the New Side Is $s - 4$, and the New Area Is:**
Understanding the Precision Behind This Simple Geometry Shift When designers adjust outdoor spaces, crafters plan precise cuts, or builders refine room dimensions, a foundational principle remains: changing a shape’s side length directly reshapes its area. For rectangles, this relationship follows a clear formula—still rooted in $s$, the original side length. Reducing each side by 4 cm creates a new side measuring $s - 4$, and with the rectangle’s area calculating as length times width, the new area becomes $(s - 4)^2$. This change—seemingly small—holds meaningful implications for efficiency, design accuracy, and cost estimation in real-world applications. Discoveries rooted in geometry influence everything from solar panel installation to interior renovation, making this calculation relevant across homes, businesses, and commercial developments throughout the U.S. --- ### Why After reducing each side by 4 cm, the new side is $s - 4$, and the new area is: Is Gaining Attention in the U.S.
