The Becker Department Store's basement is 15 feet below ground. If the total length of the building from basement to roof is 70 feet, what is the building's elevation above ground?

To find the building's elevation above ground, we need to subtract the height of the basement from the total length of the building.

Elevation above ground = Total length - Height of basement
Elevation above ground = 70 feet - 15 feet
Elevation above ground = 55 feet

Therefore, the building's elevation above ground is 55 feet.

To find the building's elevation above ground, we need to calculate the difference between the total length of the building and the depth of the basement.

Total length of the building = 70 feet
Depth of the basement = 15 feet

Elevation above ground = Total length of the building - Depth of the basement
Elevation above ground = 70 feet - 15 feet
Elevation above ground = 55 feet

Therefore, the building's elevation above ground is 55 feet.
