Question

a rectangular sheet of paper is 12 1 by 2 cm long and 10 2 by 3 cm wide find the parameter​

Answer 1

Answer:

Perimeter of a rectangle = 2( L+B )

L = 12 1/2

   = 25/2

B = 10 2/3

   = 32/3

2( L+B ) = 2( 25/2+32/3 )

2( 25/2+32/3 ) = 2( 75/6+64/6 )

                          =2( 139/6 )

                          = 2( 23.166 )

                = 46.332 cm is perimeter
