Question

2. A path 1 m wide is built inside a square park of side 30 m along its sides. Find the
of the path. Calculate the cost of constructing the path at the rate of 70 per m2​

Answer 1

Answer:

A path 1 m wide is built inside a square park of side 30 m along its sides.

The area of the path

$= 28 \times 1 \times 4 + 1 \times 1 \times 4$

$= 116 \: {m}^{2}$

The cost of constructing the path at the rate of 70 per m2 is

$= 70 \times 116 = 8120$
