4.2.1 Use the measurements given to calculate the total length of bedroom 2 in metres.

Answer :

To convert the length of Bedroom 2 from feet and inches into meters, we'll follow these steps:

  1. Convert feet to inches: First, convert the feet measurement to inches by multiplying by 12, as there are 12 inches in a foot.
    [tex]14 \text{ feet} = 14 \times 12 = 168 \text{ inches}[/tex]

  2. Add the extra inches: Add the additional inches from the original measurement to the result from step 1.
    [tex]168 \text{ inches} + 3 \text{ inches} = 171 \text{ inches}[/tex]

  3. Convert inches to meters: Using the conversion factor for inches to meters (1 inch = 0.0254 meters), multiply the total inches by this conversion factor.
    [tex]171 \text{ inches} \times 0.0254 \text{ meters/inch} = 4.3434 \text{ meters}[/tex]

Thus, the total length of Bedroom 2 in meters is approximately 4.3434 meters.
