Question

Kate made a box to hold her jewelry collection. She used 42 inches of wood to build the sides of the box. If the box was 9 Inches wide, how long was the box

Answer 1

The correct answer for the question that is being presented above is this one: "11.5 inches."

Perimeter = 2W + 2L
42 = 2(9) + 2L
42 = 19 + 2L
2L = 23
L = 11.5 inches

So the other side of the box has a length of 11.5 inches.
