Question

In a garden,there are 8 rows and 10 columns of apple trees. The distance between the two trees is 2m. And a distance of 1 mt is left from all sides of the boundary of the garden. The length of the garden in mts is

Answer 1

Each column seperation is 2 m

There are 10 columns

So seperation is 20m

Add side bundary 1 m on both side

So total length of the garden is 22m

Answer 2

Answer:

The Length of the Garden is 80 m.

Step-by-step explanation:

Given: There are 8 rows and 10 columns of apple tree in garden.

           Distance between two trees = 2 m

           Distance Between of garden and tree = 1 m

To find: Length of Garden

Length of garden = Perimeter of Rectangular shaped Garden

There are 8 rows of tree and distance between 2 trees = 2 m

⇒ Width of tree Garden = 2 × 8 = 16 m

There are 10 columns of tree and distance between 2 trees = 2 m

⇒ Length of tree Garden = 2 × 10 = 20 m

Width of boundary of garden = 16 + 1 + 1 = 18 m  ( 1 m from each sides )

Length of boundary of garden = 20 + 1 + 1 = 22 m

Perimeter of Rectangular Garden = 2 × ( Length + Breadth )

                                                         = 2 × ( 22 + 18 )

                                                         = 2 × 40

                                                         = 80 m

Therefore, The Length of the Garden is 80 m.
