Pak Budi wants to build a fence around his rectangular garden. To calculate the length of fence needed, one must first calculate the perimeter of the garden by adding the lengths of all sides. The perimeter is directly related to the cost, as a longer perimeter/fence will cost more to construct. If fencing costs Rp 25,000 per meter and the perimeter is calculated, then the total cost can be determined by multiplying the perimeter by the per meter price.
