Question

The boundary of a rectangular table with sides 2 m and 4 m is .... m

Answer 1

Required Answer :

The boundary of a rectangular table with sides 2 m and 4 m is 12 m

Explanation :

Here, we are provided with the sides of a rectangular table, i.e. 2 m and 4 m. And we need to calculate the boundary of the rectangular table. So, we will use the formula of perimeter of rectangle. Because perimeter is the sum of the sides/boundaries.

Formula to calculate perimeter of rectangle :

$\boxed{\bf Perimeter = 2(l + b)}$

where,

• l denotes the length of the rectangle
• b denotes the breadth of the rectangle

Solution :

We are given :

• Length of the rectangular table = 2 m
• Breadth of the rectangular table = 4 m

To find :

• Boundary of the rectanglular table

Solution :

Using formula,

$\boxed{\bf Perimeter = 2(l + b)}$

we have,

• l = 2 m
• b = 4 m

Substituting the given values,

$\\ : \implies\sf Perimeter = 2(l + b)$

$\\ : \implies\sf Perimeter = 2(2 + 4)$

Adding the numbers present within the brackets.

$\\ : \implies\sf Perimeter = 2(6)$

$\\ : \implies\sf Perimeter = 2 \times 6$

$\\ : \implies\sf Perimeter = 12$

Therefore, the boundary of the rectangular table = 12 m

Knowledge Bytes :

• Area of rectangle = length × breadth
• Area of square = side × side
• Perimeter of square = 4 × side
• Diagonal of rectangle = √(l² + b²)
• Diagonal of square = √2 × side

Answer 2

$\mathfrak{Solution-:}$

Given-:

• Length of a Rectangular Table = 2m
• Breadth of a Rectangular Table = 4m

To Find-:

• Perimeter of a Rectangular Table = ?

Using Formula-:

• Perimeter of a Rectangle = 2(Length + Breadth)

Calculation-:

Perimeter of a Rectangle = 2(Length + Breadth)

➢ 2 (2 + 4)

➢ 2 (6)

➢ 12m

Hence, the Perimeter of a Rectangular Table is 12m².
