The elevation of a building's basement is -12 feet. Given the building is square shaped and the total length of the building from basement to roof is 62 feet, what is the elevation of the building above ground?
picture it in your head at -12 feet elevation (12 feet below ground level), the basement starts 62 feet from that level is the roof so count 62 units up from -12 and get 50 feet above ground level (60-12=50)
