Answer 2

Calculating the New Area of the Rectangular Sports Playground

To calculate the new area of the rectangular sports playground after it has been increased in size by 3 times, we can use the formula:

New Area = (3 * Length) * (3 * Width)

Given: - Length of the original playground = 10 m - Width of the original playground = 9 m

Using the given values, we can calculate the new area of the sports playground.

Calculation

New Area = (3 * 10) * (3 * 9)

New Area = 30 * 27

New Area = 810 square meters

So, the area of the new sports playground after it has been increased in size by 3 times is 810 square meters.
