Steven is cutting an 11 ft piece of lumber into three pieces to build a triangular garden. Which diagram shows a way in which he can cut the wood to create three pieces that can form a triangle?

For three lengths to form a triangle, the sum of the two shorter sides must be greater than the longest side. In choice B, the two shorter pieces are 3 feet and 4 feet, and 3 + 4 = 7, which is greater than 4 feet. Therefore, the 3-foot, 4-foot, and 4-foot pieces can form a triangle.
