Answer 1

Answer:

₹ 1065

Step-by-step explanation:

To find the cost of levelling path. first, we need to find out the area of rectangular lawn and area of the path.

GIVEN :

LENGTH OF RECTANGULAR LAWN = 45 m

BREADTH OF RECTANGULAR LAWN = 20 m

AREA OF RECTANGULAR LAWN = L * B

= 45 * 20

= 900 sq. m

AREA OF LAWN + PATH = L* B

= 51 * 26(length =45+6, breadth = 20+6).

= 1326 sq. m

To find the area of path

= Area of (lawn+path) - area of lawn

= 1326 - 900

= 426 sq. m

Cost of levelling the path 2.50 per sq. m

= 426* 2.50

= 1065₹
