1. • Perimeter = 66 cm

   • Breadth = 15 cm

   Step-by-step explanation:

   Given:-

   • Area of Rectangle = 270 cm²
   • It’s Length = 18 cm

   To Find:–

   • It’s Breadth
   • It’s Perimeter

   Formula used:–

   • Area of Rectangle = L × B
   • Perimeter of Rectangle = 2(l + b)

   Solution:–

   Firstly,

   [tex]Area \:of\: Rectangle \:= \:L × B[/tex]

   [tex]270 \:= \:18 × B[/tex]

   [tex]B \:= \:\dfrac{270}{18}[/tex]

   [tex]{\boxed{\red{B \:= \:15\:cm}}}[/tex]

   Now,

   [tex]Perimeter\: of \:Rectangle \:= 2(l + b)[/tex]

   [tex]Perimeter \:= 2(18+ 15)[/tex]

   [tex]Perimeter\:= 2×33[/tex]

   [tex]{\boxed{\red{Perimeter\:= 66\:cm}}}[/tex]

   Hence, The Breadth and Perimeter of the given Rectangle is 15 cm and 66 cm respectively.

2. Given :-

   The area of a rectangle is 270 cm² and it’s length is 18cm.

   To Find :-

   The breadth and the perimeter of the given rectangle respectively.

   Used Concepts :-

   • Area of a rectangle i.e ” l × b ” , where l is length and b is breadth of the rectangle.
   • Perimeter of a rectangle i.e 2 × ( l + b ) , where l and b stands for as the same as the above .

   Solution:-

   Let , The Length of the rectangle = l = 18 cm

   The breadth of the rectangle = b = ?

   Area ( A ) of the rectangle = 270 cm²

   Now , According to the question ,

   l × b = A

   18 × b = 270

   b = 270/18

   b = 15 cm

   Now. , Perimeter of the rectangle = 2 × ( l + b )

   2 × ( 18 + 15 )

   2 × 33

   66 cm

   Therefore , the Breadth and perimeter of the rectangle are 15cm and 66cm respectively.
