A rectangular storage building is 30 feet long and 25 feet wide. Find the ratio of the length to the primeter of the bulding.
now I divided 30 by 25 and got 1.2 feet is that correct?
perimeter = 60+50 = 110
so ratio of
length : perimeter = 30 : 110
= 3:11
so its 3.11?
or 3 by 11 feet
It asked for the "ratio" of the length to the perimeter.
Perhaps some of these pages will help you to understand ratios.

1.2 answer....
To find the ratio of the length to the perimeter of the building, you first need to calculate the perimeter. The perimeter of a rectangular shape is obtained by adding up the lengths of all its sides.
In this case, the building is 30 feet long and 25 feet wide. To calculate the perimeter, you need to add up the lengths of the four sides:
Perimeter = 2 × Length + 2 × Width
Substituting the known values:
Perimeter = 2 × 30 feet + 2 × 25 feet
Perimeter = 60 feet + 50 feet
Perimeter = 110 feet
Now that you have the perimeter, you can calculate the ratio of the length to the perimeter:
Ratio = Length / Perimeter
Ratio = 30 feet / 110 feet
To simplify the ratio, you can divide both the numerator and denominator by their greatest common divisor (gcd). In this case, the gcd of 30 and 110 is 10:
Ratio = 3 feet / 11 feet
Therefore, the ratio of the length to the perimeter of the rectangular storage building is 3 feet to 11 feet.
