Answer 2

Calculation of the Length of the Border

To calculate the length of the border, we need to find the perimeter of the square-shaped flower bed. The flower bed has a side length of 90 cm.

The formula to calculate the perimeter of a square is:

Perimeter = 4 * side length

Substituting the given side length of 90 cm into the formula, we get:

Perimeter = 4 * 90 cm

Simplifying the calculation, we find:

Perimeter = 360 cm

Therefore, the length of the border is 360 cm.

To express this length in meters and centimeters, we can convert 360 cm to meters by dividing by 100:

360 cm = 3.6 meters

So, the length of the border is 3.6 meters and 360 centimeters.
