Question

garden is 120m long and 85m wide it has an inside path of uniform width 3.5m all around it the remaining part of the garden is covered by grass find the cost covering the garden at 50paise per square metre.

Answer 1

Solution:-
Length of the rectangular garden = 120 m and breadth = 85 m
There is path of uniform width of 3.5 m all around the garden and the rest of the part is covered with grass.
So, Length of the portion covered by grass = 120 - (3.5 + 3.5)
= 120 - 7
= 113 m
And, Breadth of the portion covered by grass = 85 - (3.5 + 3.5)
= 85 - 7 
= 78 m
So, 
Area of the portion that covered by grass = 113*78
= 8814 sq m
Area of the portion covered by grass = 8814 sq m
Cost of covering the garden by grass = rs. 0.50 per sq m
Total cost of covering the garden = 0.50 × 8814
= Rs. 4407
So, the total cost of covering the garden = Rs. 4407
