A rectangular garden has a perimeter of 600 meters. If the width is 100 meters, what is the length of the garden?

Explanation

The perimeter of a rectangle is calculated as 2 × (length + breadth). Given the perimeter is 600 m and breadth is 100 m, we have 600 = 2 × (length + 100). Dividing both sides by 2 gives 300 = length + 100, so length = 300 - 100 = 200 meters.
