Prior to hosting an international soccer match, the local soccer club needs to replace the artifical turf on their field with gr

GuDViN [60]

Answer:

It will cost $68,620.5 to the club to add the grass turf to their field.

Explanation:

length of the field = l = 0.102 km = 0.102 × 1000 m

( 1km = 1000 m)

Width of the field w = 0.069 km = 0.069 × 1000 m

Area of the field , A= l × w

$A=0.102\times 1000 m\times 0.069\times 1000 m=7,038 m^2$

Cost of grass turfing = $9.75 \$/m^2$

Cost of grass turfing on field of $7,038 m^2$ :

$=7,038 m^2\times 9.75 \$/m^2=\$68,620.5$

It will cost $68,620.5 to the club to add the grass turf to their field.
