₹4608

Step-by-step explanation:

$length \: of \: the \: football ground \: along \: with \: the \: flower \: bed \: = (80 + 2 + 2)m = 84m$

$breadth \: of \: the \: football \: ground \: along \: with \: the \: flower \: bed =( 60 + 2 + 2)m = 64m$

$area \: of \: the \: football \: ground \: along \: with \: the \: flower \: bed = 84 m \times 64m$

$= 5376 {m}^{2}$

$area \: of \: the \: football \: ground \: alone = 80m \times 60m$

$= 4800 {m}^{2}$

$\therefore \: area \: of \: the \: flower \: bed \: alone = (5376 - 4800) {m}^{2} = 576 {m}^{2}$

So, the area of the flower bed is 576m²

$cost \: of \: gardening \: 1 {m}^{2} flowerbed = ₹8$

$\therefore \: cost \: of \: gardening \: the \: whole \: flower \: bed = ₹8 \times 576$

$= ₹4608$

Therefore, the cost of gardening the whole flower bed is ₹4608
