Hello friend,
Perimter of square= 4 × sides
= 4× 1.2cm= 4.8 cm
As per question perimters are same,
Permiter of equilateral triangle= 3 × sides
4.8cm/3 = side
1.6 = side.

Answer 2

side of equilateral triangle is 4 cm

area of square 1.2*4=4.8cm
area of square=area of triangle
so 3side of triangle=4.8
side=4.8/3=1.6
