Question

A part 4m wide runs along inside a square park of side 80 find the area of the part and also find the cost of cementing at rs 120per sq.m

Answer 1

For park with Path
S = 80 m
Area = 80²
= 6400m²
For park without path
S = 80 -4 -4
= 72 m
Area = 72²
=5184 m²
Area of Path = 6400 - 5184
=1216 m²
cost per m² = Rs 120
Total cost = 1216 × 120
=145929 Rs
