Area of rectangle= 40 cm×22cm= 880cm^2
Now its rebend into square so
Area of □= side ^2
880cm^2= side^2
28.6 cm= side

here's ur answer....
perimeter of rectangle=perimeter of square
perimeter of rectangle=2(l+b)
=2(40+22)
=2×62
=124cm
therefore perimeter of square=124cm
hence, length of the side of square=124/4
=31cm
area of rectangle=l×b
=880cm²
area of square=side×side
=31×31
=961cm²
square encloses more area by=961-880
=81cm²
hope this helps...
