Question

a path 1 m wide is built inside a square park of side 30 m along its sides. find the answer of the path. calculate the cost of constructing the path at the rate of ₹ 70 per m
​

Answer 1

Answer:

8120m^2

Step-by-step explanation:

side of square park (A) = 30m

  width of path  = 1m

  side of inner park (a) = 30-1-1 = 28m

  cost of construction = 70 per m^2

 

  Area of path = Area of square park - area of park inside the path  

                       = A^2  -  a^2

                       = 30^2 - 28^2

                       = 900 - 784

                       = 116m^2

 Cost of construction of path  = 70×116

                                               =8120m^2 pls mark as brainlist
