Answer 1

HEY HERE IS YOUR ANSWER☺☺☺

Length of wire = 12 cm.

i) As we know in an equilateral triangle all the sides are equal . So , the length of each side = 12/3 = 4 cm.

ii) As we know in a square all the sides are equal . Hence the length of each side of square = 12/4 = 3 cm.

HOPE IT HELPS ☺☺☺

Answer 2

It is given that,

Length of the wire ( l ) = 12 cm

i ) If the wire is bent as an equilateral triangle.

Let each side of the equilateral triangle = x cm

Perimeter ( P ) = lenth of the wire

3x = 12 cm

x = 12/3

x = 4 cm

Therefore ,

Length of the side = x = 4cm

ii ) If wire is bent into the shape of a square ,

Perimeter of the square = length of the wire

4 × side of each side( s ) = 12 cm

s = 12/4

s = 3 cm
