Answer 2

Answer:

★ The total cost of paving the path is Rs.9150

Step-by-step explanation:

Given:

• A square field, 300 m long, is bordered on the outside by a path of width 5 m

To Find:

• Find the cost of paving the path at ₹150 per 100 sq.m.

Solution:

★ We Know that :

• The side of the square is 300m
• The path of width 5m is surrounded

★ Now the dimensions :

• of each side of the square field with the field will be

⋆ 300m + 5m + 5m

⋆ 300m + 10m

⋆ 310m

∴ The measure of each side of the field with the path is 310m

★ Formula used :

• Area of a square = Side × Side

★ Now the area of :

• The field along with the path will be

⋆ Side × Side

⋆ 310m × 310m

⋆ 96100m

• The square field will be

⋆ Side × Side

⋆ 300m × 300m

⋆ 90000m

★The area of the path will be :

• 96100m - 90000m
• 6100m

∴ The area of the path is 6100m

★The cost :

• For paving the path = 6100 × 150 / 100
• For paving the path =  9150

Therefore:

• The total cost of paving the path is Rs.9150
