Answer:
A rectangular sheet of paper is 12 1/2 cm long and 10 2/3 cm wide. What is its perimeter and area?
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.

133.325
Step-by-step explanation:
PLEASE MARK ME AS BRAINLIEST
LENGTH : 12.5 cm
BREADTH : 10.666 cm
FORMULA OF PERIMETER : 2(l + b)
PERIMETER = 2( 12.5 + 10.666 )
= 2 * 23.166
= 46.332
FORMULA OF AREA : l + b
AREA = 12.5 * 10.666
= 133.325
