The length of a square shaped garden is 40 m. The length and breadth of another rectangular garden are respectively 50 m and 30 m. Find the perimeter of both gardens. Which garden has more area and by how much? Show answer with proper steps and diagram.​

Answer»

Answer :-

Given :-

  • Length of SQUARE garden is 40 m.

  • Length and breadth of rectangular garden are 50 m and 30 m RESPECTIVELY.

To Find :-

  • Perimeter of both gardens.
  • Which garden has more area.

Solution :-

Square :-

\begin{gathered}\begin{gathered} \sf40 \: m \: \: \: \: \: \: \: \: \: \: \: \\ {\boxed{\begin{array}{}\bf { \red{}}\\{\qquad \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:  \: \: \: \: \: \: \: \:  }{}\\ { \sf{ }}\\ { \sf{ }} \\ \\ { \sf{ }}\end{array}}} { \sf\:40 \: m} \end{gathered}\end{gathered}

Perimeter of square = 4 × SIDE

= 4 × 40

= 160

Perimeter of square = 160 m

Area of square garden = Side × Side

= 40 × 40

= 1600

Area of square garden = 1600 m²

Rectangle :-

\begin{gathered}\begin{gathered} \sf 50\:m \: \: \: \: \: \: \: \: \: \: \: \\ \boxed{\begin{array}{}\bf { \red{}}\\{\qquad \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:  }{}\\ { \sf{ }}\\ { \sf{ }} \\ \\ { \sf{ }}\end{array}} \sf\:30\:m \end{gathered}\end{gathered}

Perimeter of rectangle = 2 ( Length + Breadth )

= 2 ( 50 + 30 )

= 160

Perimeter of rectangle = 160 m

Area = Length × Breadth

= 50 × 30

= 1500

Area of rectangular garden = 1500 m²

Area of square garden > Area of rectangular garden

Area of square garden - Area of rectangular garden = 1600 - 1500

= 100

Square garden is 100 m more than that of rectangular garden.
