Question

the are of a rectangle is 650 cm,sq and its breadth is 13 cm. the perimeter of the rectangle is ​

Answer 1

✴ Given :

• Area of a rectangle is 650 cm² .Its one side is 13 cm.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

✴ To Find :

• Perimeter of rectangle .

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

✴ Solution :-

Formula Used (Rectangle) :

$\large{\orange{\bigstar}}\: \: \:{\underline{\boxed{\red{\sf{ Area = Length \times Breadth}}}}}$

$\large{\orange{\bigstar}}\: \: \:{\underline{\boxed{\red{\sf{ Perimeter = 2(Length + Breadth)}}}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

Length of Rectangle :

$\dashrightarrow{\qquad{\sf{ Area = Length \times Breadth}}}$

$\dashrightarrow{\qquad{\sf{ 650 = Length \times 13}}}$

$\dashrightarrow{\qquad{\sf{ Length = \dfrac{650}{ 13}}}}$

$\dashrightarrow{\qquad{\sf{ Length = \cancel\dfrac{650}{ 13}}}}$

$\large{\qquad{\blue{\longrightarrow{\underline{\red{\tt{\: Length = 50 \: cm}}}}}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

Perimeter of Rectangle :

$\dashrightarrow{\qquad{\sf{ Perimeter = 2(Length + Breadth)}}}$

$\dashrightarrow{\qquad{\sf{ Perimeter = 2(50 + 13)}}}$

$\dashrightarrow{\qquad{\sf{ Perimeter = 2 \times 63}}}$

$\large\qquad{\red{:\longmapsto{\underline{\boxed{\purple{\tt{ Perimeter = 126 \: cm}}}}}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

Therefore :

❝ Perimeter of the rectangle is 126 cm. ❞
