Does Bigger Perimeter Mean Bigger Area?
Both diagrams represent models for a backyard patio. Both diagrams use the same number of identical concrete pieces (not drawn to scale). The area of each patio is the same, 180 square meters. What are the dimensions of a single rectangle piece of concrete?
Hints:
- Notice how the pieces fit together in the second model. What is different about the way they fit together in the first model?
- The formula to find the area of a rectangle is A=l*w
- Rectangles with different perimeters can have the same area; don’t let the pictures fool you!
- Try setting up a ratio and then do a substitution.
