Answer 2

➤ Given :-

Length of the sheet :- 5${\tt\dfrac{2}{3}}$ cm

Breadth of the sheet :- 3${\tt\dfrac{1}{5}}$ cm

➤ To Find :-

Perimeter of the rectangular sheet

➤ Formula required :-

${\large \tt \dashrightarrow \orange{\boxed{\tt \gray{2 \: (Length + Breadth)}}}}$

➤ Solution :-

Perimeter of the rectangular sheet :-

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

Convert them into improper fractions so that the calculation becomes easier

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

Convert them into like fractions by taking the LCM of the denominators i.e, 3 and 5

LCM of 3 and 5 is 15.

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

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

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

${\tt \longrightarrow 2 \: \bigg(\dfrac{133}{15} \bigg) = 2 \times \dfrac{133}{15}}$

${\tt \longrightarrow \dfrac{2}{1} \times \dfrac{133}{15} = \dfrac{2 \times 133}{1 \times 15}}$

${\tt \longrightarrow \dfrac{266}{15} = 17 \dfrac{11}{15}}$

$\Huge\therefore$ The perimeter of the rectangular sheet is ${\tt 17 \dfrac{11}{15}}$.
