Question

Apart 1 metre wide is built inside a square Park of side 30 M along its sides find the areas of the path calculate the cost of constructing the path at the rate of 70 per metre square

Answer 1

Area of square park = (side)^2
= (30)^2
= 900m^2
After making the path
side of small square = 28m
area of small square = (side)^2
= (28)^2
= 784m^2
therefore,
area of path = ( 900-784)m^2
= 116m^2
Cost of constructing the path at the rate of rupee 70 per m^2
= 70*116
= 8120 rupees
.... I hope it will help you

Answer 2

Answer:

Step-by-step explanation:

side of square park=30m

width of park= 1m

side of inner park =30-1-1m

=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

therefore cost of construction = ₹70 × 116

=₹ 8120
