Question

Plssss help! Find the perimeter of each polygon. Assume that lines which appear to be tangent.

Answer 1

11) 75.2

12) 44.2

Explanation:

angles formed by intersecting lines tangent to a circle are the same length.

11)

Perimeter = 2(5) + 2(12) + 2(11.4) + 2(9.2) = 75.2

12)

Perimeter = 2(4) + 2(8) + 2(5.3) + 2(4.8) = 44.2
