uniform width 3 5m all around it the remaing part of the garden is
covered by grass find the cost of covering the garden by grass at
50 paise per square meter

Shreyas Hari · Answer

Area of a path around a rectangle = AB - ab A and B are the sides
of the outer rectangle
a and b are the sides of the inner rectangle
[120 cm * 85 cm]-[(120-3 5)*(85-3 5)]
=10200-[116 5*81 5]
=10200-9494 75
=205 252
Now to find the cost:
205 25*50 paise
​=1026250 paise or 10262 50 Rs
