Answer 2

Given,

Perimeter of rectangular garden $\[ = 46cm\]$

Solution,

Know that length is 4 cm more than the breadth of rectangular garden.

Consider the breadth of garden is b.

So length of garden is (b+4).

Perimeter of garden $\[{\rm{ = 2}}\left( {{\rm{length + breadth}}} \right)\]$

Put the values according to the question,

$\[\begin{array}{l}\frac{{{\rm{2}}\left( {{\rm{b + 4 + b}}} \right)}}{2} = 46\\ \Rightarrow 2b + 4 = 46\\ \Rightarrow 2b = 42\\ \Rightarrow b = 21\end{array}\]$

Breadth of rectangular garden

$\[ = 21cm\]$

Length of rectangular garden,

$\[\begin{array}{l} = 21 + 4\\ = 25cm\end{array}\]$

Hence, the length and breadth of rectangular garden is $\[25cm\]$ and $\[21cm\]$ respectively.
