Answer 1

Answer:

Given:

Diagonal =32cm , Base=8cm , side=6cm

⇒Area of square 

=21×(d)2

=21×(32)2=512cm2

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

⇒ 2512=256cm2

∴ Area of paper required =256  cm2

⇒For triangle III region

⇒S=26+6+8=10cm

⇒A=s(s−a)(s−b)(s−c)  

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

⇒A=4×25cm2=17.92  cm2

Area of paper required for III triangle shade=17
