The perimeter of the patio in feet is 60 feet.
According to the question,
We have the following information:
Deana made a scale drawing of her patio using scale of 1/2cm = 1 foot. The length is double the width of the patio.
We have to find the perimeter of the patio in feet when width of the patio is 5 cm.
So, we will convert this into feet.
5 cm = 2*5 feet
5 cm = 10 feet
Now, the length of the patio will be:
2*width
2*10 feet
Length of the patio = 20 feet
Now, the patio is in the form of rectangle.
Perimeter of rectangle = 2(length+width)
Perimeter of rectangle = 2(20+10)
Perimeter of rectangle = 2*30 feet
Perimeter of rectangle = 60 feet
Hence, the perimeter of the patio in feet is 60 feet.
