A Farmer Leans a 12 ft Ladder Against A Barn. The Base of the Ladder Is 3ft From The Barn. l To The Nearest Foot, How High on the Barn Does The Ladder Reach?

A.) 11ft B.) 12ft. C.) 13ft. D.) 14 ft

If Someone Can Answer This, Id Really Appreciate it!

The ladder, wall, and the floor makes a right triangle with the hypotenuse equal to the length of the ladder. Let h be the height in the wall of the barn that the ladder reached and applying the Pythagorean theorem,

(12 ft) ² = h² + (3 ft) ²

The value of h is equal to 11.62 ft. Thus, the ladder reached up to 11.62 ft of the wall.

Its actually 11.62 which is approx. 12 feet
