A building is 2 ft from a 12-ft fence that surrounds the property. A worker wants
to wash a window in the building 16 ft
from the ground. He plans to place a
ladder over the fence so it rests against
the building. (See the figure.) He
decides he should place the ladder 12
ft from the fence for stability. To the
nearest tenth of a foot, how long a
ladder will he need?
4 ft
12 ft
12 ft
2 ft
He will need a ft ladder.
(Type an integer or decimal rounded to the nearest tenth as needed.)
