The area of a rectangle is calculated by multiplying length by width, resulting in an area of 686 m² for the town square. Its perimeter is calculated using the formula 2l + 2w, with the town square perimeter being 113.4 meters. When comparing areas of different shapes, use their respective formulas and compare the results.
To find the area of a rectangle, like the town square mentioned, you use the formula Length × Width. So, with a length of 39.2 meters and a width of 17.5 meters, the area would be
.
The perimeter of a rectangle is found with the formula
, where 'l' is the length and 'w' is the width. For the town square, the perimeter would be
.
When comparing areas of different shapes, like squares with squares or circles with squares, you use the respective formulas for each shape and compare the results. For a square, the area is side² and the perimeter is 4 × side.
