Question

A rectangular sheet of paper is 11×1/2cm long and 10×2/3cm wide. Find its perimeter.

Answer 1

☆ Given:-
==============================================

Length of a rectangular sheet of paper (l) = (11 * 1)/2 cm

= 11/2 cm

Breadth of a rectangular sheet of paper (b) = (10 * 2)/3 cm

= 20/3 cm
==============================================

☆ Calculation:-
==============================================

Perimeter of a rectangular sheet of paper = 2(l + b)

= 2(11/2 + 20/3)

= 2 * (33 + 40)/6

= (2 * 73)/6

= 146/6

= 24.3 cm Ans.
==============================================

Ans.) Its perimeter is 24.3 cm.
