1-2

you got 163m². ( area covered with grass)

then multiple area with .5 rupees. ( paise change into rupees)

you will got 81.5 rupees

Answer 2

length of a Garden = 120 - 7 = 113

breadth of a garden = 85 - 7 =75 m

Area of garden = l * b

= 113 * 75

= 8475 m2

breadth of a path = 3.5 m

cost of covering grass = 50 paise

= 3.5 m * 0.5 paise

= 1.60 paise

cost of covering = 8475 m2 *1.60 paise

= rupees 1356.00
