What is the perimeter of the composite figure? Round to the nearest tenth

125.5 units

Step-by-step explanation:

The vertices of the composite figure has been named A to F.

*See attachment below.

Thus, Perimeter of ABCDEF =

= |-12 - 6| = 18 units

= |-12 - 3| = 15 units

= |6 - 15| = 9 units

= |-12 - 24| = 36 units

= |-12 - 18| = 30 units

Thus, Perimeter of ABCDEF = 18 + 15 + 9 + 17.5 + 36 + 30 = 125.5 units
