The correct option is B 372⋅58 sq. m
Given,A wire when bent in the form of a square encloses an area of 484 sq. m .
Area of Square=(side)2
or, 484 =(side)2
or, side =√484=22cm
Perimeter of square= 4 × side
= 4 × 22
= 88 cm.
When same wire is formed into equilateral triangle,then perimeter of square is equals to perimeter of triangle.
∴ Perimeter of equilateral triangle= 88 cm
or, 3× side = 88 cm
or, side = 883cm.
Area of equilateral triangle thus formed =√3×(side)24
=√3×(883)24
=372.58cm2
