अवधारणा:

वर्ग का क्षेत्रफल = (वर्ग की भुजा)2

गणना:

दिया गया है:

शीट की विमा = 1 m × 1 m = 1000 mm × 1000 mm

वर्ग की विमा = 20 mm × 20 mm

शीट से काटे जा सकने वाले वर्गों की संख्या = \(\frac{Area~of~the~sheet}{Area~of~the~square}\)

⇒ शीट से काटे जा सकने वाले वर्गों की संख्या = \(\frac{1000~\times~1000}{20~\times~20}\)

⇒ शीट से काटे जा सकने वाले वर्गों की संख्या = 2500
