6 The perimeter of a rectang flar table is 18 feet. The table is 42 inches wide. Which of the following show the length of the table? \( (1 \) foot \( =12 \) inches \( ) \)

To find the length of the rectangular table, we start by converting the table's width from inches to feet. The width is 42 inches, which equals \( \frac{42}{12} = 3.5 \) feet. The formula for the perimeter \( P \) of a rectangle is given by \( P = 2l + 2w \), where \( l \) is the length and \( w \) is the width. Substituting the known values we have: \[ 18 = 2l + 2(3.5) \] This simplifies to: \[ 18 = 2l + 7 \] Subtracting 7 from both sides gives: \[ 11 = 2l \] Finally, dividing by 2, we find: \[ l = 5.5 \] Thus, the length of the table is 5.5 feet. Now you know how to convert inches to feet, and remember, math can sometimes feel like a puzzle! Keep practicing those measurements; soon enough, it’ll feel as easy as pie!
