Question

A path 3.5 m wide runs inside along the boundary of a square field whose side is 65 m.
Find the area of the path. Also find the cost of manuring the rest of the field at the rate
of 25 per square metre.
​

Answer 1

=> Side of outer sq = 65 m

=> Width of path = 3.5 m

=> Cost of measuring = 25 rupees / sq metre

=> Side of inner sq = 65 - ( 2 × 3.5 )

=> 58 m

=> Area of path = 65 × 65 - 58 × 58

=> 4225 - 3364

=> 861 sq metre

=> Cost of measuring the rest 9f the field = 3364 × 25

=> ₹ 84100

Answer 2

Answer:

Side of outer sq = 65m

width of path = 3.5m

cost of measuring = 25 rupees/sq metre

side of inner sq = 65 - (2 * 3.5)

= 58m

area of path. = 65 * 65 - 58 * 58

= 4225 - 3364

= 861 sq metres

cost of measuring the rest of the field = 3364 * 25

= ₹ 84100
