Question

a rectangular sheet of paper is 12 1/2 cm long and 10 2/3 wide what is the perimeter

Answer 1

Answer: 66.33cm

Step-by-step explanation:

Perimeter = 2(length + breadth)

                = 2(12$\frac{1}{2}$ + 10$\frac{2}{3}$)

                =2( 12+10+$\frac{7}{6}$)

                = 2(12+10+1+$\frac{1}{6}$)

                = 2(23$\frac{1}{6}$)

                 = 2 x 23$\frac{1}{6}$

                 =2 x $\frac{139}{6}$

                 = $\frac{139}{3}$

                 =66.33cm
