❍ Let the length of rectangle be 2x cm and breadth of rectangle be x cm respectively.

\underline{\bigstar\boldsymbol{According\;to\;the\;given\;Question:}}

  • The length of a rectangle is twice than the breadth let the value be 2x
  • Perimeter of rectangle is 36 cm.

\underline{\frak{ \pink{\dag\;As\;we\;know\;that:}}} \\  \\    \red{\bigstar} \:  {\underline{\boxed {\sf{Perimeter \: of \: rectangle = 2(l + b)}}}}

Applying the values,

 \twoheadrightarrow \sf{36 = 2(2x + x)} \\  \\ \twoheadrightarrow \sf{36 = 4x + 2x} \\  \\ \twoheadrightarrow \sf{36 = 6x} \\  \\ \twoheadrightarrow \sf{x =   \cancel{\frac{36}{6}}} \\  \\ \twoheadrightarrow  \underline{\boxed{\frak{x = 6}}} \red \bigstar \\  \\

Therefore,

  • The length of rectangle is 2x = 2 × 6 = 12cm
  • The breadth of rectangle is x = 6 cm
