Question 5
A rectangular photo (RBSESolutions.com) whose length 2\(\frac { 3 }{ 4 }\) inch and breadth \(\frac { 7 }{ 6 }\)inch. Find its perimeter.
Solution:
Length of rectangular photo = 2\(\frac { 3 }{ 4 }\) = \(\frac { 11 }{ 4 }\) inch
and breadth of rectangular photo = 2\(\frac { 7 }{ 6 }\) inch
∴ P = 2(l + b)


∴ Perimeter of rectangular photo = \(\frac { 47 }{ 6 }\) = 7 \(\frac { 5 }{ 6 }\) inch.
