Rectangular lawn has 80 metre metre and 60 metre has two roads each 10 metre wide running in the middle of 81 parallel to the length and the other parallel to the breed find the cost of gravelling them at rs 1.20 per square metre
Answers
Total Cost of graveling the road is Rs.1560
Step-by-step explanation:
Given :
Dimensions of rectangular lawn = 80 m x 60 m
Width of the roads = 10 m
Area of the rectangle = Length x Breadth
Area of the roads = (10 x 80) + (10 x 60) - (10 x 10 ) (roads ║ length and width of field)
= 800 + 600 - 100 = 1300 m²
Cost of graveling the road is Rs.1.20 per m²
Total cost of graveling the road = 1300 x 1.20 = Rs. 1,560
