Design three different rectangles that all have an area of 36 square units. Compare their perimeters.
Explain why a 4×6 rectangle and a 3×8 rectangle have different areas even though 4+6 = 3+8.
Create a complex shape using exactly 20 unit squares. Calculate its area and explain your design.
Investigate: If you double the length and width of a rectangle, how does the area change?
A farmer wants to fence a rectangular garden with 28 square units of area. What dimensions minimize fencing?
Compare these methods for finding area: counting squares vs. using length × width. When is each better?
