Question

find the missing length.
assume that all intersecting sides meet at right angles.
include the correct unit in your answer.

Explanation:

Step1: Analyze the vertical sides

The total vertical length on the left - hand side is \(15\) ft. The sum of the two non - missing vertical segments on the right - hand side is \(4 + 7\) ft.

Step2: Calculate the missing length

Let the missing length be \(x\). Using the property of right - angled intersecting sides (the sum of vertical lengths on one side equals the sum of vertical lengths on the other side), we have \(x=15-(4 + 7)\).
