Answer:
Length of material needed = 35.8 feet
Step-by-step explanation:
Door of the wooden garage is in the shape of a rectangle with dimensions 16 ft × 8 ft.
Lincoln is going to place two boards in the shape of an X on the door.
From the picture attached,
Diagonals of the rectangular door will be equal in measure.
Therefore, length of the material = 2×(Diagonal of the rectangle)
By applying Pythagoras theorem in the rectangle,
(Diagonal)² = 16² + 8²
Diagonal = = 17.89
Therefore, length of material = 2 × 17.89
= 35.77
≈ 35.8 feet
