Question

7. What is the area of the shape at right? What is the perimeter of this shape?:
X2 x 1

Answer 1

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
`39.2 m * 17.5 m = 686 m^2`.

The perimeter of a rectangle is found with the formula
`P = 2l + 2w`, where 'l' is the length and 'w' is the width. For the town square, the perimeter would be
`2 * 39.2 m + 2 * 17.5 m = 113.4 meters`.

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.
