Answer 2

Calculation of the Area and Perimeter of the Sports Hall

To find the area and perimeter of the sports hall, we need to know the width and length of the hall. According to the given information, the width of the sports hall is 20 meters, and the length is twice the width.

Let's calculate the area and perimeter of the sports hall:

Step 1: Calculate the Length of the Sports Hall The length of the sports hall is twice the width, which means it is 2 times 20 meters. Length = 2 * 20 meters = 40 meters

Step 2: Calculate the Area of the Sports Hall The area of a rectangle is calculated by multiplying its length and width. Area = Length * Width = 40 meters * 20 meters = 800 square meters

Step 3: Calculate the Perimeter of the Sports Hall The perimeter of a rectangle is calculated by adding the lengths of all its sides. Perimeter = 2 * (Length + Width) = 2 * (40 meters + 20 meters) = 2 * 60 meters = 120 meters

Therefore, the area of the sports hall is 800 square meters, and the perimeter is 120 meters.

Please note that the information provided above is based on the given dimensions of the sports hall and the calculations performed.
