a rectangular field is 80 m long and 60 M wide A 4 m wide is constructed outside the field around it find the area of road
Answers
To find :
We have to find the area of the road of 4 m width which is constructed outside the rectangular field of 80 m length and 60 m width.
Answer :
Area of the road is 1184 m²
Step by step solution :
• Step 1 (Area of the field)
Length of the field, l = 80 m
Width of the field, b = 60 m
Area of the field
= length × width
= 80 × 60 m²
= 4800 m²
• Step 2 (Area of the whole plot)
Length of the field together with the road
= 80 + (2 × 4) = 88 m
Width of the field together with the road
= 60 + (2 × 4) = 68 m
So, the area of the field together with the road
= 88 × 68 m² = 5984 m²
• Step 3 (Area of the road)
Therefore, the area of the road
= Area of the field together with the road - Area of the field
= 5984 - 4800 m²
= 1184 m²
{ See the attachment for the required figure }
Anwer: 1184m^2
Correct answer: 1184m^2

I have solved question in 3 steps. there are 3 independent images for independent step.
1st step: Area of field
=> L × B
=> 80 × 60m^2
=>. 4800m^2
2nd step: Length and width of field with road
=> 88m and 68m
3rd step: Area
=> 88 × 68m^2
=> 5984m^2
Area of filed with road - Area of road
=> 5984 - 4000m^2
=> 1184 m^2
