An ALS community center in barangay Linao measures 20 meters long and 15 meters wide. What is its perimeter?
The perimeter of a rectangle is calculated by adding the lengths of all sides. In this case, the perimeter of the ALS community center can be calculated by adding twice the length and twice the width of the rectangle.
Perimeter = 2(length + width)
Perimeter = 2(20 + 15)
Perimeter = 2(35)
Perimeter = 70 meters
Therefore, the perimeter of the ALS community center is 70 meters.
