Answer 1

Answer:

• 231 m²
• ₹ 4620

Step-by-step explanation:

See the attached.

The path goes along the perimeter of the park and parallel to the sides, something like the picture attached.

The path is 1 m wide and the total length is:

• 50*3 + 30*3 = 240 m

We need to consider the dark cells points in the picture with reflects the overlaps. They are counted twice and each is 1 m x 1 m.

Subtracting the duplicated area 9 x 1 m² to get the total area of the path:

• 240 - 9 = 231 m²

The cost of cementing is:

• 231*20 = 4620
