Question

The cost of constructing a road is Rs.5000 per 100 m^2.Find the cost of constructig a road 5m broad surrounding a garden 100m long and 10m broad.

Answer 1

As given
₹5000 per 100m^2 and hoe much fpr 1m^2
=5000/100
=50
By imagination we can find that the road cannot passed from length so the road can be passed through breadth so the area of road
= 5 × 10
=50m^2
so 1m^2 = ₹50
= 50m^2
= ₹2500

Answer 2

Answer:60000

Step-by-step explanation:

in the given figure are of garden is 1000^2

Now,

      the breath of the road = 110m

       the length of the road =20m

Therefore, the area =110*20m^2

                                 =2200m^2

now, the area of the road = 2200-1000m^2

Therefore , the area f the road = 1200m^2

Now,

       cost =1200*5000/100

                =12*5000

                 =60000rs -ANSWER
