Question

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

Explanation:

Step1: Analyze horizontal sides

The sum of horizontal sides on the left - hand part and the bottom part should equal the top - most horizontal side. Let the missing vertical side be $x$. The top - most horizontal side is 13 yd, and the sum of the known horizontal sides is 9 + 4=13 yd.

Step2: Analyze vertical sides

The sum of vertical sides on the left - hand part should equal the sum of vertical sides on the right - hand part. The left - hand vertical sides are 5 yd and 6 yd, so their sum is 5 + 6 = 11 yd.

Answer:

11 yd
