Question

The length of a rectangle field is 200m and it breath is 1/4 of its length. If a road of width 5m is built long the inner wall of the field,what is the area of the field.

Answer 1

Answer:

Step-by-step explanation:

Area of the road = Area of whole field - Area of the inner field

(area of the inner field an be found by subtracting 10m from both the sides in length and breadth..so 300-20 will be the length and 200 - 20 will be the breadth of the inner field)

                          =            (300× 200)  -  (280 × 180)    

                          =             60000m - 50400m

                          =             9600 m²

∴ Area of the road = 9600 m²
