Question

A rectangular sheet of paper is 15 upon 3/4 cm long and 12 upon 1/2 cm wide. find its perimeter.​

Answer 1

Answer:

perimeter of rectangle = 2(l +b)      where l = length

                                                                  b = breadth

given,

l = 12 1/2 , b = 15 3/4

perimeter = 2( 12 1/2 + 15 3/4)

              = 2( 25 / 2 + 63 / 4)

              = 2(50 + 63)/ 4

              = 2( 113/ 4)

              = 113/2

              = 56.5 cm
