Given :-
A square lawn has 2 m wide path surrounding it.
Area of the path = 136m²
To Find :-
The area of the lawn.
Analysis :-
Consider the side length of lawn as a variable.
The area of path is the difference between area of square path and area of lawn.
Then make an equation and get the value of the variable accordingly.
Solution :-
We know that,
- s = Side
- a = Area
Given that,
Area of outer square - Area of inner square = Area of the path
Let us consider the side of the lawn to be 'x'. Then, the side length of path is x + 4
As per the given info,
Finding the value of x,
Therefore, the length of lawn is 15 cm.
By the formula,
Given that,
Side (s) = 15 cm
Substituting their values,
Area = 15²
Area = 225 cm²
Therefore, the area of the lawn is 225 cm².
