Answer 1

$\large\bf\underline\red{Answer \: :-}$

Given :

• Length of rectangle is 50m.

First we find breadth

Required Formula

${\small{\underline{\boxed{\textsf{\textbf{\red{Perimeter= 2(l+b) }}}}}}}$

According to the Formula

$\sf\longrightarrow{500 = 2(50 + b)} \\ \\ \sf\longrightarrow{500 = 100 + 2b} \: \: \: \: \: \: \: \: \: \\ \\ \sf\longrightarrow{2b = 500 - 100} \: \: \: \: \: \: \: \: \\ \\ \sf\longrightarrow{2b = 400} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf\longrightarrow{2b = \frac{400}{2} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \bf\longrightarrow \red{breadth = 200m}$

Now,

• Length = 50m
• Breadth = 200m

Finding Area of rectangle

Required Formula

${\small{\underline{\boxed{\textsf{\textbf{\red{Area = Length × Breadth}}}}}}}$

According to the Formula

$\sf\longrightarrow{Area =50 \times 200 } \: \: \: \: \\ \\ \bf\longrightarrow \red{Area =10000m {}^{2} }$

Answer :

• Area = 10000m²
• Breadth = 500m
