Area of whole square sheet = 40² = 1600 cm²
One side of the inner square = 40 - (5+5) = 30 cm
Area of the inner square = 30² = 900 cm²
Area of the strip cut out = 1600 - 900 = 700 cm²
One side of the inner square = 40 - (5+5) = 30 cm
Area of the inner square = 30² = 900 cm²
Area of the strip cut out = 1600 - 900 = 700 cm²
