Enlarging Images by Percents
If you want to enlarge something by a percent, the perimerter and the side length will be increased by that percent, but the area will be different. For example: if you want to increase a square of 16 sq in. by 25%, you would need to find the side length so you can find the perimeter. You can multiply that by 4 since there are 4 sides of a square. The side length would be 4 sq in. for the original figure so the perimeter would be 16 sq in. To find the perimeter of the figure enlarged be 25%, you enlarge the sides by 25%. The enlarged figure's side would be 5 sq in. so the perimeter would be 5x4=20 sq in. To find the area, you would multiply the base and the height. That would be 5x5=25 in. sq. Don't forget about Mug Wump, Zug Wump, Lug Wump, Bug Wump, and Glug Wump, the video game! Remember that on the coordinates of the game characters, "start over" means literally pick up your pencil.
