Question

a rectangular sheet of paper is 12 1 by 2 cm long and 10 2 by 3 cm wide find its perimeter​

Answer 1

Step-by-step explanation:

length of the rectangular sheet = 12 1/2 cm

breadth of the rectangular sheet= 10 1/2 cm

perimeter of a rectangle = 2(l+b)

= 2(12 1/2 + 10 1/2)

= 2(23/2+21/2)

= 2(23+21/2)

= 2(44/2)

= 2*22

=44 cm^2..
