Question

A rectangular piece of paper is 12 1/2 m long and 10 2/3 cm wide. Find the perimeter.

Answer 1

Answer:

139/ 3

Step-by-step explanation:

Perimeter of Rectangle = 2x(l+b)

   Perimeter of Rectangle = 2X(12 1/2+10 2/3)

   Therefore Convert Mixed Fraction into Improper Fraction

=  12 1/2 = 25/2 &

=  10 2/3 = 32/3

=  2X(25/2+32/3)

=  For adding the fractions: Find LCM of Denominators(2&3)

=  LCM = 6

=  2X (25X3 + 32X2) = 75 + 64

          (2X3      3X2  )         6

=  2X139 = 278 = 139

          6        6         3

= Therefore: Primeter of Rectagular Sheet= 139 / 3

                                                                     

Answer 2

Answer:

417

Step-by-step explanation:

perimeter of rectangle = 2 ( l + b )

lenth = 12 1/2

width = 10 2/3

Perimeter = 2 × ( 12 1/2 + 10 2/3 )

2 × ( 75 + 64 / 6 )

2 × 139 / 6
