Question

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

Answer 1

Step-by-step explanation:

clearly

area of path will be difference between areas of outer square and inner square

side of outer square = 30 m

path is 1m wide

so side of inner square will be 30 - 2*1 = 28 m

area of path = 30^2 - 28^2

= 58*2

= 116 SQM

cost of construction

= 70*116

= 8120 rupee
