Question

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

Answer 1

Answer:

First find area of path

$(65 + 3.5×2)(65 + 3.5×2) - 65 \times 65 = 959{m}^{2}$

So cost will be = 25 × 959 = ₹23975

Answer 2

Step-by-step explanation:

Answer:

→ Area of the path = 861 m² .

Step-by-step explanation:

Given :-

→ Width of path = 3.5 m .

→ Side of square park along with path = 65 m .

To find :-

→ Area of the path .

Solution :-

∵ Side of square park without the path = 65 - ( 2 × 3.5 )  =  58 m .

Now, area of square park alnog with path

= side × side .

= ( 65 × 65 ) m² .

= 4225 m² .

And, area of square park without path

= side × side .

= ( 58 × 58 ) m² .

= 3364 m² .

Therefore, area of the path = ( 4225 - 3364 ) m² .

= 861 m² .

And, cost of measuring the rest of the field = ==== 3364 × 25 .

= ₹86100 .

Hence, it is solved .
