Question

A rectangular sheet of paper is 5 2/3 cm long and 3 1/5 cm wide. find its perimeter ​

Answer 1

Correct Question:-

A rectangular sheet of paper is $\sf{5 \dfrac{2}{3}}$ cm long and $\sf{3 \dfrac{1}{5}}$ cm wide. Find its perimeter?

Answer:-

The perimeter of the rectangular sheet is 17.733cm

Step-by-step explanation:-

To Find:-

• The perimeter of the sheet .....(?)

Solution:-

We know that,

Perimeter of a rectangle = 2 ( Length + Breadth )

Given that,

Length of the rectangular sheet is $\sf{5 \dfrac{2}{3}}$ cm

Breadth of the rectangular sheet is $\sf{3 \dfrac{1}{5}}$ cm

Therefore, by putting the values,

$\sf{\longrightarrow \: 2 \bigg({5 \dfrac{2}{3} +\sf{3 \dfrac{1}{5}} \bigg) }}$

$\sf{\longrightarrow \: 2 \bigg({ \dfrac{17}{3} +{\dfrac{16}{5}} \bigg) }}$

$\sf{\longrightarrow \: 2 \bigg({ \dfrac{(5 \times 17) + (3 \times 16)}{15} \bigg) }}$

$\sf{\longrightarrow \: 2 \bigg({ \dfrac{85 + 48}{15} \bigg) }}$

$\sf{\longrightarrow \: 2 \bigg({ \dfrac{133}{15} \bigg) }}$

$\sf{\longrightarrow \: \dfrac{266}{15} }$

$\sf{ \longrightarrow \: 17.73 \: \: or \: \: 17 \dfrac{11}{15}}$
