Answer 1

area of square
side square
2^2
4cmsqare
area of rectangle
l*b
3*2
6cmsquare
area of equilateral triangle
√3/4*Side square
√3/4*4sqare√3/4×16
√12
approximate
3.5cmsquare
area of rec t angle is greater

Answer 2

area of square =s^2
=2^2
=4cm^2
area of rectangle=lb
=3x2
=6cm^2
area of equilateral triangle=bh/2
b=4,h=x
h=√(4^2+2^2)
=√(16+4)
=√20
=2√5cm
area=(4x2√5)/2
=(8√5)/2
=4√5cm^2
hence area of rectangle is more
