Given :-

  • Side of the Square park = 100m
  • Wide of the Path = 5m

 \\  \\

To Find :-

  • Area of the Path

 \\  \\

Solution :-

Area of the Square Park

➞ Area of the Square park = (Side)²

➞ Area of the Square park = Side × Side

➞ Area of the Square park = 100 × 100

➞ Area of the Square park = 10000m²

________________

Side of the Garden

➞ Side of the Garden = 100 - 5 + 5

➞ Side of the Garden = 100 - 10

➞ Side of the Garden = 90m

________________

Side of the Garden

➞ Area of the Garden = (Side)²

➞ Area of the Garden = Side × Side

➞ Area of the Garden = 90 × 90

➞ Area of the Garden = 8100m²

________________

Area of the Path

➞ Area = Park's Area - Garden's Area

➞ Area = 10000 - 8100

➞ Area of the Path = 1900m²

________________

Therefore, Area of the Path = 1900m²

Given:

  • A square park has the side 100m

  • A path of 5m wide is made inside the garden all around.

\\ \\

To Find:

  • The area of the path

\\ \\

Solution:

\\ \\

◐ Now here, we have got the side of the square which is 100m and siad that there is a path made of 5m all around the square and we have to find the path.

\\ \\

Now,

↦ The area of path equals the area of the outer square - inner square.

\\ \\

Let's find the area of outer square

\\ \\

{ : \implies} \sf \: area \: of \: a \: square =  {side}^{2}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\  \\  \\ { : \implies} \sf \: area \: of \: the \: square =  {100}^{2}    \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \: \\  \\  \\  \\ { : \implies} \sf \: area \: of \:the\: square = 10000 {m}^{2}  \bigstar

\\ \\

hence,

the area of the outer square equals 10000m²

\\ \\

★Now we find the value of the inner square★

As a path of 5 m is made so, the sides of the inner square are reduced by 5 m from both the sides of a side.

\\ \\

{ \longrightarrow }\sf \: side \: of \: the \: inner \:  square = 100 - (5 - 5) \\  \\  \\\longrightarrow \:  \sf \: side \: of \: the \: inner \:  square = 100 -10 \:  \:  \:  \:  \:  \:   \\  \\  \\ \longrightarrow\sf \: side \: of \: the \: inner \:  square = \orange{90m \bigstar} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\\ \\

Now , as we found the side of the inner square let's substitute it and find the area

\\ \\

{ : \implies} \sf \: area \: of \: a \: square =  {side}^{2}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\  \\  \\ { : \implies} \sf \: area \: of \:the \: square =   {90}^{2}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\  \\  \\ { : \implies} \sf \: area \: of \: the \: square = 8100 {m}^{2}

\\ \\

❍ hence,

the area of the inner square equals 8100m²

\\ \\

Now let's find the area of the path

\\ \\

 { : \implies} \sf \: area \: of \: the \: path \:  = 10000 - 8100 \\  \\  \\  \\  { : \implies} \sf \: area \: of \: the \: path \:  =  \pink{ \underline{ \boxed{1900 }\bigstar}} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\\ \\

therefore, the area of the path equals 1900m²

\\ \\
