Question

a path 2m wide runs along inside a square park of side 100m. Find the cost of cementing it at the rate of ₹250 per 10m^2​

Answer 1

Answer:

width is 2m

length is 100m

area =2×100m²

= 200m²

the cost of cementing at rate per 10m²=₹250

the cost of cementing at rate 200m² =₹250/10m²×200m²

=₹5000

Answer 2

★ Question :-

A path 2m wide runs along inside a square park of side 100m. Find the cost of cementing it at the rate of ₹250 per 10m^2.

★ Answer

★ Given :-

• A square park of side 100 m.
• A path 2 m wide runs along inside a square park.

★ To Find :-

• The cost of cementing it at the rate of ₹250 per 10m².

★ Formula used :

• Area of square = (side)²

★ Solution :-

Dimension of park :-

Side of park = 100 m

Area of park = (side)² = (100)² = 10000 m².

Now, A path 2m wide runs along inside a square park of side 100m.

So, inner Dimension of square

Side of inner square = 100 - 2 - 2 = 96 m

So, Area of inner square = (side)² = (96)² = 9216 m²

★ So, Area of path = Area of park - Area of inner square

Area of path = 10000 - 9216 = 784 m²

Cost of cementing path for 10 m² = ₹ 250

Cost of cementing path for 1 m² = ₹ 25

★ Cost of cementing path for 784 m² = 25 × 784 = ₹ 19600
