side of a square is =20 cm
then area of square is = 400cm ^2
area of rectangle is = 400 cm^2
l×b =400
l×10=400
l=40
length is 40cm
perimeter is = 2(l+b)
= 2(40+10)
= 2(50)
=100 cm
therefore length of a rectangle is 40cm and perimeter of it is 100cm
then area of square is = 400cm ^2
area of rectangle is = 400 cm^2
l×b =400
l×10=400
l=40
length is 40cm
perimeter is = 2(l+b)
= 2(40+10)
= 2(50)
=100 cm
therefore length of a rectangle is 40cm and perimeter of it is 100cm
