A is 1cm = 7.5 ft
B is 1cm = 3.75 ft
Above are two different models of the same pentagon. If the length of side B is 38 cm, what is the length of side a?
To find the length of side A, we first need to convert the length of side B from cm to ft using the scale given:
1 cm = 3.75 ft
38 cm = 38 cm * 3.75 ft/cm
38 cm = 142.5 ft
Now that we have the length of side B in feet, we can use the scale for side A to find its length:
1 cm = 7.5 ft
x cm = 142.5 ft
Solving for x:
x = 142.5 ft / 7.5 ft/cm
x = 19 cm
Therefore, the length of side A is 19 cm.
