How to find the perimeter of a diagram

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

a) 10 ft. B) 25%. C) 56.3% increase

Step-by-step explanation:

8 * 25% = 2, so new length of Each side is 10 Ft

Since all sides grew by 25% length, the perimeter changed 25% also

The new area Is 10x10 = 100 100/64 = 1.563
