Question

A rectangular sheet of paper is 12 1/2cm long and 10 2/3 cm wide. Find its perimeter

Answer 1

GIVEN:

• Length of rectangular sheet = 121/2 cm
• Breadth of rectangular sheet = 102/3 cm

TO FIND:

• What is the perimeter of the rectangular sheet ?

SOLUTION:

We have given that, the length of rectangular sheet is 121/2 cm and breadth of rectangular sheet is 102/3 cm

• Length = 121/2 cm
• Breadth = 102/3 cm

We know that the formula for finding the perimeter of rectangular sheet is:-

$\large{\boxed{\bf{\star \: PERIMETER = 2(L+B) \: \star}}}$

According to question:-

On putting the given values in the formula, we get

$\rm{\hookrightarrow Perimeter = 2 \Bigg( \dfrac{121}{2} + \dfrac{102}{3} \Bigg) }$

$\rm{\hookrightarrow Perimeter = 2 \Bigg( \dfrac{363+204}{6} \Bigg)}$

$\rm{\hookrightarrow Perimeter = \cancel{2} \times \dfrac{567}{\cancel{6}} }$

$\rm{\hookrightarrow \cancel\dfrac{567}{3} }$

$\bf{\hookrightarrow Perimeter = 378 \: m}$

❝ Hence, the perimeter of rectangular sheet is 378 m ❞
