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 total horizontal length should be equal on both sides. The top horizontal segment is 5 ft, and there's another horizontal segment of 6 ft. So the total horizontal length (let's call it \( L \)) is \( 5 + 6 = 11 \) ft. Wait, no, actually, for the vertical side, the total height is 16 ft, and one part of the vertical side is 6 ft (the height of the lower rectangle). Wait, maybe I mixed up. Let's look at the vertical sides. The total height of the figure is 16 ft. The lower part (the height of the bottom rectangle) plus the upper part (the height of the top rectangle) should equal 16 ft. The upper part's height: wait, the horizontal segments: the bottom horizontal side (let's call it \( y \)) should be equal to the sum of the top horizontal segments. Wait, the top has two horizontal segments: 5 ft and 6 ft? Wait, no, the figure is an L - shape. So for the horizontal direction, the length of the bottom side ( \( y \)) should be equal to the sum of the two horizontal segments on the top: 5 ft + 6 ft = 11 ft? Wait, no, maybe vertical. Wait, the total vertical length is 16 ft. The height of the lower rectangle is \( y \) (wait, no, the left side has a segment labeled 6 ft and then the rest? Wait, maybe the missing side is the bottom horizontal side. Wait, let's re - examine. The figure has right angles, so the horizontal lengths on the top (5 ft and 6 ft) should add up to the length of the bottom horizontal side ( \( y \) ). So \( y=5 + 6=11 \) ft? Wait, no, maybe vertical. Wait, the total height is 16 ft. The height of the lower rectangle is \( y \) (wait, the left side has a segment of 6 ft, and then the upper part. Wait, maybe the vertical side: the total height is 16 ft, and the height of the upper rectangle is 6 ft? No, the left side has a segment labeled 6 ft, and then the upper part. Wait, maybe the missing side is the bottom horizontal side. Let's consider the horizontal dimensions. The top horizontal segments are 5 ft and 6 ft, so the bottom horizontal side ( \( y \)) should be \( 5 + 6 = 11 \) ft. Wait, but let's check the vertical. The total height is 16 ft. The height of the lower rectangle: if the upper rectangle's height is \( 16 - 6=10 \) ft? No, maybe I got it wrong. Wait, the problem is to find the missing side length. Let's look at the horizontal sides. The two horizontal segments on the top (5 ft and 6 ft) should sum to the length of the bottom horizontal side ( \( y \) ). So \( y = 5+6 = 11 \) ft? Wait, no, maybe the vertical. Wait, the total height is 16 ft. The height of the lower part (the rectangle at the bottom) is \( 16 - 6=10 \) ft? No, the left side has a segment of 6 ft, and then the upper part. Wait, maybe the missing side is the bottom horizontal side, and the calculation is \( 5 + 6 = 11 \) ft. Wait, let's do it properly. In a right - angled L - shaped figure, the sum of the horizontal lengths on one side equals the horizontal length on the opposite side, and the sum of the vertical lengths on one side equals the vertical length on the opposite side. For the horizontal direction: the top has two segments, 5 ft and 6 ft. So the bottom horizontal side ( \( y \)) should be \( 5 + 6=11 \) ft. For the vertical direction: the total height is 16 ft, and the height of the lower rectangle is \( 16 - 6 = 10 \) ft? Wait, no, maybe the missing side is the bottom horizontal side. Let's confirm. If we look at the horizontal edges, the top edge is composed of two parts: 5 ft and 6 ft. So the bottom edge (which is the missing side) should be equal to the sum of these two parts. So \( 5+6 = 11 \) ft.

Step2: Calculate the missing side

The missing side (the bottom horizontal side) is the sum of the two horizontal segments on the top. So \( 5+6 = 11 \) ft.

Answer:

11 ft
