Question

A Square of side of 40 cm and a rectangle of length 50 cm has same perimeter. which has greater area

Answer 1

side of square =s^2

=40^2

=1600cm^2
perimeter of square=4×s

=4×40
=160cm
so
perimeter of reactangle=2(l+b)

160 =2(50+b)
160/2 =50+b
80-50=b

b=30.
now,
area of ractangle=l×b

=50×30
=1500cm^2

hence area of square is greater
