Consider a rectangular lawn measuring 20 meters by 10 meters, yielding an initial area of 200 square meters. A circular flowerbed with a 2-meter radius resides within the lawn. Its area ( * 2 12.57 square meters) must be subtracted from the initial 200 square meters, resulting in a usable lawn area of approximately 187.43 square meters. This adjusted area forms the basis for accurate material calculations. Similarly, a shed or a paved pathway necessitates similar adjustments to prevent overestimation and ensure efficient resource use. Failure to account for obstacles, regardless of their size or shape, introduces inaccuracies that cascade through subsequent calculations, affecting material quantities, cost estimations, and overall project success.
