Angle ABC and angle DEF are complementary angles. The measure of angle ABC is twice the measure of angle DEF. Write an equation to find x, the measure of angle DEF, and then solve for x.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
