length of the wire= perimeter of the rectangle
perimeter of rectangle
- 2(l+b)
- 2(40+22)
- 2(62)
- 124 cm
thus l of wire= 124 cm
l of wire= perimeter of square
perimeter of square
- 4*side= p
- 4*side= 124 cm
- side= 124 / 4
- side= 31 cm
Thus each side of the square will be 31 cm.
I think u meant to ask which FIGURE has more area
Area of rectangle= l*b=40*22=880 cm square
Area of square= side*side= 31*31=961 cm square
Therefore, the SQUARE has more area.
Done! :)
Plz mark as brainliest! Hope this helped.. :)))
