Question

5.
A 2.5m wide road runs inside a square field of side 65 m along its boundary. This road is to be gravelled and in paristo
laid with grass. If the cost of gravelling is Rs 1.50 per mand the cost of laying the grass is Rs 0.50 per, find the list
​

Answer 1

Step-by-step explanation:

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 ) = 58Now, area of square park alnog with path

= side × side .

= ( 65 × 65 ) m² .

= 4225 m² .

And, area of square parkwithout path

= side × side .

= ( 58 × 58 ) m² .

= 3364 m² .

Therefore, area of the path = ( 4225 - 3364 ) m² .And, cost of measuring the rest of the field = 3364 × 25 .

= ₹86100 .

Hence, it is solved .

Answer 2

Answer: ₹86100

Step-by-step explanation:

Therefore, area of the path = ( 4225 - 3364 ) m² . And, cost of measuring the rest of the field = 3364 × 25 . = ₹86100 . Hence, it is solved .
