Step-by-step explanation:
The sheet of paper is 12 1/2 cm long and 10 2/3 cm wide. Or
the length = 25/2 cm and the width = 32/3 cm.
The perimeter of the sheet of paper = 2[(25/2) + (32/3)]
= 2[75+64]/6
= 2*139/6
= 46.33 or 46 1/3 cm. Answer.
Its area = (25/2)(32/3) = 133.33 or 133 1/3 sq.cm. Answer.
