Question

A rectangular lawn of length 50 M and breadth 30 M is to be surrounded externally by a path which is 2m wide find the area of the path .

Answer 1

We have,
length of the lawn=50m
It's breadth. =30m

area of the rect. lawn=length*breadth
=50m *30m=1500m^2

now,
we have breadth of the complete lawn and the path=30m+2m+2m=34m

then,we have total length=50m+2m+2m=54m

Total rectangular area =length*breadth
=54m*34m
=1836m^2

Now,
The area of the path=Total area-area of the lawn

=1836m^2-1500m^2
=336m^2

We get ,the area of the path is 336m^2.

Answer 2

Step-by-step explanation:

length of lawn =50 m

breadth of lawn = 30 m

Area of the rectangle lawn= l * b

50m *30m

1500M *2

now,

we have breadth of the lawn and the path

= 30+ 2m +2m = 34m

Then , we have total length = 50+2 +2 =54m

total rectangular area = l*b

34*54 =1836m ^2

1836m^2 - 1500

= 336
