Question

find the perimeter of the composite figure. the figure is not drawn to scale. identify the four labeled side lengths in the figure.

Explanation:

Step1: Analyze the figure

By observing, we can find that the vertical - side lengths sum and horizontal - side lengths sum are equal to the perimeter of a rectangle.

Step2: Calculate the perimeter

The length of the equivalent rectangle is 12 m and the width is 12 m. The perimeter formula of a rectangle is $P = 2\times(l + w)$. Here, $l=12$ m and $w = 12$ m. So $P=2\times(12 + 12)=48$ m.

Answer:

48 m
