Find the area and perimeter of the yellow portion.
the squares in the yellow figure are larger than the others and have a side- length of 2 units

We have 2 squares with side length of 2 units. In each square is a circle that is cut into 4 pieces and moved to make the design shown. We know the circle would take up the whole square because the edges of all the pieces touch each other. So we know the circles diameter is 2 units. We need to find the area of the square and then subtract the area of the circle to find the yellow area. Then we multiply it by 2 because there are 2 of them.

Area of square = 2×2=4 units squared.

Area of circle = 3.14(1)^2 = 3.14 units squared.

4 - 3.14 = .86 × 2 = 1.72

The area of the yellow is 1.72 units squared.
