Question

solve question no. 4

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
