Question

The boundaries of a square of side $6\text{cm}$ and a rectangle of sides $6\text{cm}$ and $8\text{cm}$ were to be covered by a ribbon. What is the total length of ribbon required?

• A. $50\text{cm}$
• B. $48\text{cm}$
• C. $52\text{cm}$
• D. $36\text{cm}$

Answer 1

The correct option is C $52\text{cm}$

Lengths of all sides of the square $=6\text{cm}$
Perimeter of square $=4\times$ length of sides $=4\times 6=24\text{cm}$
Length of the rectangle $=8\text{cm}$
Breadth of the rectangle $=6\text{cm}$
Perimeter of rectangle $=2\times (\text{length}+\text{breadth})$
$=2\times (8\text{cm}+6\text{cm})$
$=2\times 14\text{cm}$
$=28\text{cm}$

Length of ribbon required $=24\text{cm}+28\text{cm}=52\text{cm}$
