Answer 1

Answer:

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

=8120
