Question

if perimeter of square and rectangle are equal, which will have more area? 

Answer 1

perimeter of square=4l
perimeter of rectangle=2(l+b)
2l+2b=4l
2b=2l
so l=b
so area of rectangle=area of square

Answer 2

the area of square will be more

 for example... let the perimeter be 10 m

therfore side of square will be 2.5 m
and l and b  of rectangle can be 3 and 2 respectively or it can be 4 and 1 respectively

the area of square will be 6.25 sq.m.

the area of rectangle can be 3 x 2 = 6 sq.m. or it can be 4 x 1 = 4 sq.m.
