Red Seal Carpenter Practice Exam

If a finished window size (outside of jamb to outside of jamb) is 1 220 mm x 720 mm (48" x 28") and its center is located at 4 400 mm (14' 5") from the SE corner of a house, at what mark from the SE corner will the window side of the closest trimmer be located?

1. 3 180 mm

2. 3 777.5 mm

3. 3 790 mm

4. 3,797.5 mm

The correct answer is: 3,797.5 mm

To determine the location of the closest trimmer to the window, it is essential to take into account the size of the window and its position relative to the SE corner of the house. First, the finished size of the window is 1,220 mm wide (which is 48 inches) x 720 mm high (which is 28 inches). The window's center is located 4,400 mm from the SE corner. The window's width means that its center is also exactly in the middle of the window, which provides a critical measurement point to locate the trimmers. Since the window is 1,220 mm wide, the distance from the center of the window to one side is half of the window's width, which is 610 mm (1,220 mm / 2). Because we want to find the mark where the side of the closest trimmer will be located, we subtract this distance from the total distance from the SE corner to the center of the window. Starting from the center position of 4,400 mm and subtracting 610 mm gives us the following calculation: 4,400 mm - 610 mm = 3,790 mm. This is the mark from the SE corner where the side of the
