i. What can be the possible expression for the length of the grass area?

ii. What can be the possible expression for the breadth of the grass area?

iii. Find the length and breadth of the rectangular grass area by taking x = 5 units.

Answer 1

Answer:

Step-by-step explanation:

Length PQ = (40 + 2 + 2 ) m = 44 m

Breadth QR = ( 25 + 2 + 2 ) m = 29 m

∴ Area of PQRS = 44 m x 29 m = 1276 m2

Now,

Area of the path = Area of PQRS − Area of the lawn ABCD

= 1276 m2 − 1000 m2

= 276 m2

Rate of levelling the path = Rs. 8.25 per m2

∴ Cost of levelling the path = Rs. ( 8.25 x 276)

= Rs. 2277
