HEYA MATE !! HERE IS YOUR ANSWER:
Step-by-step explanation:
Solution:-
Let the outer rectangle be ABCD and the inner rectangle be abcd.
Length and Breadth of the outer rectangle = 120 meter and 85 meter.
The uniform width of the inside path is 3.5 meter,
So, the length of the inner rectangle = 120 - 7 = 113 m
and the breadth of the inner rectangle = 85 - 7 = 78 m
The area of the inner rectangle = 113 × 78 = 8814 m²
Cost of covering the garden by grass = Rs 0.5 per square meter.
The total cost of covering the garden by grass = 0.5 × 8814
= Rs 4407

RE: SHINCHAN
Answer:
Rs. 90
Step-by-step explanation: Please mark it as the brainliest
Total length of the path=perimeter of the garden
=2(100+80)m
= 2*180m
= 360m or 36000 cm
Width of the path= 2.5 cm
Therefore, area of the path= length*breadth
= (36000*2.5) sq.cm
= 90000 sq.cm or 9 sq.m
Therefore, cost of covering the path with red gravel at Rs. 10/sq.m=Rs.(9*10)
= Rs. 90
