Answer 2

Answer:

length of small lawm ABCB = 30 m

brearh of small lawm ABCB = 25 m

Step-by-step explanation:

Area of large lawn = 30*25

= 750 m^2

wide = 2.5 m

length of large lawn =(30+2*2.5)m

= 35 m

breath of large lawn = (25 +2*2.5)

= 30 m

Area of large lawn PQRS = 35* 30

= 1050 m^2

Area of path = Area of large lawn PQRS - Area of large lawn

= 1050 m^2 - 750 m^2

300 m^2

1m^2 cost = RS 8.25

cost of 300 m^2 = 8.25 * 300

= Rs 2465
