Given:

Diagonal =32cm , Base=8cm , side=6cm

⇒Area of square = 1/2 ×(d)² = 1/2 × (32)²

= 512cm²

⇒Area of shaded portion I = Area of shaded portion II

⇒ 512/2 = 256cm²

∴ Area of paper required = 256 cm²

⇒For triangle III region

⇒S = 6+6+8 / 2 = 10cm

⇒A= √s(s−a)(s−b)(s−c)

⇒Area = √10(10−6)(10−6)(10−8) = √10×4×4×2 cm²

⇒A = 4 × 2√5 cm² = 17.92 cm²

Area of paper required for III triangle shade = 17.92 cm²
