60 per m.
A square lawn is surrounded by a path 2.5 m wide. If the area of the path is 165 m². find
the area of the lawn.
The length and breadth of a rectangular park are in the ratio 5:2. A 2.5-m-wide path
the nork has an area of 305 m2. Find the dimensions o​

Answer 1

Answer:

answer = 196m square

Step-by-step explanation:

Consider the side of the lawn be x

Given width of the path 2.5m

Side of the lawn including path x+2(2.5)=x+5

Area of a square =(side)

2

So, area of lawn = (Area of the lawn including the path) - (Area of the path)

Therefore, According to the given question,:

x

=(x + 5)

−140=−10x

−140=−10x

i.e 140=10x

∴x=140/10=14

Since the side of the lawn = 14m

The area of the lawn=(14)

or196 m
