Perimeter of rectangle = 2(l+b)
150/2 = (l+b)
l+b = 75
150/2 = (l+b)
l+b = 75

Perimeter = 150cm
[tex]2(l+b)=150 [/tex]
l+b=75 -----1
l=33+b (l is generally longer lol)
l-b=33----2
1+2 gives
l+l+b-b=75+33
2l=108
l=54cm
l+b=75
b=75=l
=75-54
=21cm
So if the length is 54 cm, breadth is 21cm, if length is 21cm, breadth is 54cm
