Question

On a landscaper's plans for a garden, the scale is .5 in : 10 ft. On the plans, the main sidewalk is 3 1/2 in. long. What is the actual length of the sidewalk?

Answer 1

`\text { Ratio = } 0.5 \ \text { in } : 10 \text { ft}`

---------------------------------------------------------------------------------
Find 1 inch :
---------------------------------------------------------------------------------


`1 \ \text { in } : 10 / 0.5 \text { ft}`


`1 \ \text { in } : 20 \text { ft}`

---------------------------------------------------------------------------------
Find 3 /12 inches :
---------------------------------------------------------------------------------

`1 \ \text { in } : 20 \text { ft}`


`3 (1)/(2) \ \text { in } : 20 * 3 (1)/(2) \text { ft}`


`3 (1)/(2) \ \text { in } : (20)/(1) * (7)/(2) \text { ft}`


`3 (1)/(2) \ \text { in } : 70 \text { ft}`

---------------------------------------------------------------------------------
Answer: The actual length of the sidewalk is 70 feet.
