Answer:
40
Explanation:
First, find the length of the rectangle. We know the width is 4, and the ratio of the width to length is 2:5, making the width ratio four, it is 4:10. Therefore, the length of the rectangle is 10. Since the pentagon is regular, and one side of the pentagon is 4, multiply 4 by 4 =16. Then we can find the perimeter of the figure: 16+ 10 + 10 + 4 = 40.
