5.1.1 Area of the built rectangle

To find the area of a rectangle, simply multiply its length by its width. For example, if your rectangle is 5 meters long and 3 meters wide, the area would be 5 x 3 = 15 square meters. This straightforward formula can be applied to any rectangle, making it super handy whether you’re calculating the size of a garden plot, a room, or even a tiny pizza! But beware of common mistakes! A frequent error is forgetting to use the same units of measurement. If your length is in meters and your width is in centimeters, you might end up with a confusing area figure. Always convert your measurements to the same unit before multiplying to avoid those pesky errors!
