Formula used: Area of square =( side )2 Diagonal =√2×( side ) Calculation: Let a nad A be the side of n identical square and large square. Diagonal of square =A√2 ⇒A√2=m ⇒A=m∕√2 Area of large square = sum of the area of small square ⇒A2=n×a2 ⇒m2∕2=n×a2[∵A=m∕√2] ⇒a=m∕√(2n) ∴ The side of the smaller square sheet is m∕√(2n).
