6. Sarah is planning to fence in her backyard garden. One side of the garden is 34 feet long, another side is 30 feet long, and the third side is 67 feet long. If the fencing material costs $3.00 per foot, how much will Sarah's fence cost?

A.$154.00

B.$938.00

C.$750.00

D.$393.00

D. $393.00

Step-by-step explanation:

We have to sum the three distances to get the perimeter.

P = 34 ft + 67 ft + 30 ft

P = 131 ft

And each foot of material cost $3.00

we get the cost with the distance and de cost of the material:

Cost = 131 ft * 3.00 $ per ft = $393.00

Sarah needs $393.00 to fence her backyard garden
