according to question
pr of square=pr of rectangle
4*60=2 (80+x)
240=160+2x
x=40
now.
area of square=3600
area of rectangle=80*40=3200
so , large is square
pr of square=pr of rectangle
4*60=2 (80+x)
240=160+2x
x=40
now.
area of square=3600
area of rectangle=80*40=3200

perimeter of rectangle=perimeter of square
let breadth in rectangle be x
perimeter of rectangle=2 (l+b)
perimeter of square=4a
2 (l+b)=4a
2 (80+x)=4×60
160+2x=240
2x=240-160
2x=80
x=40
area of rectangle=l×b
=80×40
=3200
area of square=a^2
=60^2
=3600
**area of square is larger than area of rectangle.
