Calculation of the Area of the Dance Hall

To calculate the area of the dance hall, we need to know the length and width of the hall. In this case, we are given that the width of the dance hall is 20 meters, and its length is 15 meters longer than the width.

Let's calculate the length of the dance hall first. Since the length is 15 meters longer than the width, we can add 15 to the width to find the length:

Length = Width + 15 = 20 + 15 = 35 meters.

Now that we have the length and width of the dance hall, we can calculate the area by multiplying the length and width:

Area = Length * Width = 35 * 20 = 700 square meters.

Therefore, the area of the dance hall is 700 square meters.
