More than 3 solved examples on foot (ft).

Example 1: John is 6 feet tall. How many inches is he?

Solution: To convert feet to inches, we use the formula: Inches = Feet x 12. Therefore, John's height in inches is 6 x 12 = 72 inches.

Example 2: A rectangular room measures 10 feet by 12 feet. What is the area of the room in square feet?

Solution: The area of a rectangle is calculated by multiplying its length and width. Therefore, the area of the room is 10 feet x 12 feet = 120 square feet.

Example 3: Sarah wants to convert her height from feet to meters. She is 5 feet 6 inches tall. What is her height in meters?

Solution: First, we need to convert the inches to feet. Since there are 12 inches in a foot, 6 inches is equal to 6/12 = 0.5 feet. Therefore, Sarah's height in feet is 5 + 0.5 = 5.5 feet. To convert feet to meters, we use the formula: Meters = Feet x 0.3048. Thus, Sarah's height in meters is 5.5 x 0.3048 = 1.6764 meters.
