Answers
Area of the roads is 627 m²
Area of the field not covered by the road is 10,573 m²
Cost of road construction is Rs. 43,890
Step-by-step explanation:
Given :
Length of the rectangular field = 112 m
Breath of the rectangular field = 100 m
Width of the road = 3 m
Area of the rectangle = Length x Breadth
Area of the roads = (3 x 112) + (3 x 100) - (3 x 3 ) (roads ║ length and width of field)
= 336 + 300 - 9
= 627 m²
Area of the rectangular field = 112 x 100 = 11200 m²
Area of the field not covered by the road = Area of the field - Area of the road
= 11200 - 627 = 10,573 m²
Cost of road construction = 627 x 70 = Rs. 43,890
