PLS ANSWER PLS NEED IT ​

Answer 1

Answer:

Step-by-step explanation:  ⇒ Length of the rectangle sheet = 12   1 / 2  cm

⇒Breadth of the rectangle sheet = 10    2 / 3 cm

To find :-

⇒Perimeter = ?

Sol ;-  

⇒ Perimeter of rectangle  =         2   (  l  +  b  )

                                        ⇒   {  2  ( 25 / 2  + 32  /3  }

                                        ⇒  {   2  ( 75 / 6  +  64  /  6  }  

                                         

                                        ⇒ 2 × 139 /  6  

 

                           

                                        ⇒   139   /  3  = 3 1/46  cm

Therefore the answer is ;- 3   1 /46  cm
