Question

a rectangular sheet of paper is 12 1/2 cm long and 10 2/3 cm wide. Find its perimeter

Answer 1

Perimeter=2*(length+breadth)
=2*(12 1/2 +10 2/3)
=2*(25/2+32/3)
=2*(75/6+64/6)
=2*(139/6)
=139/3
=46 1/3 cm

Answer 2

L= 12.5 cm
B=10.6

perimeter(rectangle)=2(l+b)
=2(12.5+10.6)
=2(23.1)
P=46.2cm
