Find the perimeter of a square with side lengths of 3x + 1. Use the distributive property to write an expression. (explain it too, I'll give brainlest.)​

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).
