3) .A 4m wide path runs outside and around a rectangular park of length 120m and 60m , Find area of the path
Answers
Step-by-step explanation:
area of path =area of outer path - are of inner path
= (120×60) - (120-8× 60-8)
= 7200- 5824
= 1376 Sq.cm
Given,
A 4m wide path runs outside and around a rectangular park of length 120m and 60m.
To find,
The area of the path.
Solution,
We can simply solve this mathematical problem using the following process:
As per mensuration;
Area of a rectangle
= length × breadth
According to the question;
The area of the rectangular park
= length × breadth
= 120 m × 60 m
= 7200 m^2
Now, according to the question;
The length of the rectangle formed by the park and the path all around
= (length of the park) + 2(width of the path)
= (120 m) + 2(4 m)
= 120 m + 8 m
= 128 m
And, the breadth of the rectangle formed by the park and the path all around
= (breadth of the park) + 2(width of the path)
= (60 m) + 2(4 m)
= 60 m + 8 m
= 68 m
So, the area of the rectangle formed by the park and the path all around
= length × breadth
= 128 m × 68 m
= 8704 m^2
So, the area of the path
= (area of the rectangle formed by the park and the path all around) - (area of the rectangular park)
= (8704 m^2) - (7200 m^2)
= 1504 m^2
Hence, the area of the path is equal to 1504 m^2.
