In order to calculate the cost of landscaping, first we find the total area to be landscaped and then multiply it with the cost per unit of landscaping.

Step 1 - Calculate Area

Area of the Garden (in Sq.m) = Length X Width

`= 115 xx 80`

`= 9200`

Step 2 - Calculate the total cost of laying grass

Coat of Laying Grass = Area X Cost per Sq.m

`= 9200 xx 15`

`= 138000`
