Question

a rectangular sheet of paper is 15 whose 3 upon 4 cm long​

Answer 1

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

Answer 2

56.5 cm is the answer
