Answer 1

Area of a Square

( Side )² or ( Diagonal )² / 2

Area of Equilateral Triangle

( a²√3 ) / 4

Total area of paper

Area of Square + Area of Equilateral Triangle

Solving

Area of Square = ( 30 )² / 2 = 450 cm²

Area of Equilateral Triangle = ( 32√3 ) ( √3 ) / 4

= 24 cm²

( Given : Diagonal of square is 30cm.

a² = 32√3 )

Answer

Area of Square + Area of Equilateral Triangle

450 cm² + 24 cm²

474 cm²

So, total area of paper used is 474 cm².
