Question

find the perimeter of a rectangle if its length=
9cm and breadth = 12 mm​

Answer 1

Answer:

PERIMETER OF A RECTANGLE =2[L+B]

Step-by-step explanation:

given length=9cm and breadth=12mm

we know that 1cm=10mm

so, length =90×10 =90mm

          ∵ perimeter of the rectangle=2[90+12]

                                                            =2[102]                                                                     ∴PERIMETER OF THE RECTANGLE = 204
