The length of a parallelogram exceeds its breadth by 30 cm. If the perimeter of the parallelogram is 2 m 60 cm, find the length
Nuetrik [128]

\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}

\longrightarrow \sf{2(1 + b) = 260}

\longrightarrow \sf{2(x+30+x) = 260}

\longrightarrow \sf{ 2x+30 = \dfrac{260}{20} }

\longrightarrow \sf{2x + 30 =130}

\longrightarrow \sf{2x = 130 - 30}

\longrightarrow \sf{2x = 100}

\longrightarrow \sf{x=  \dfrac{100}{2} }

• \longrightarrow \sf{b= \underline{50cm}}

\longrightarrow \sf{= x + 30}

\longrightarrow \sf{= 50 + 30}

• \longrightarrow \sf{ \underline{80cm}}

\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}

\large\bm{Breadth= \: 50cm}

\large\bm{Length= \: 80cm}
