To solve this problem, I need to calculate the area and perimeter for each of the six rectangles shown. Let me work through each one carefully.
The formulas are:
- Area = length × width
- Perimeter = 2 × (length + width)
Let me go through each rectangle:
1) Rectangle 1: 6cm × 2cm
- Area = 6 × 2 = 12 square cm
- Perimeter = 2 × (6 + 2) = 2 × 8 = 16 cm
2) Rectangle 2: 5mm × 3mm
- Area = 5 × 3 = 15 square mm
- Perimeter = 2 × (5 + 3) = 2 × 8 = 16 mm
3) Rectangle 3: 5m × ? (need to check dimensions)
Looking at the image, it appears to be 5m × some value. Let me assume it's 5m × 4m based on typical worksheet problems
- Actually, I need to be more careful. The third rectangle shows "5m" but I can't clearly see the other dimension from my analysis
Let me reconsider - I should focus on what I can clearly identify and provide the method so the student can apply it to any dimensions they see.
Actually, looking more carefully at standard worksheet formats:
3) Likely 5m × 4m or similar
4) Likely 8ft × some value
5) 6cm × some value
6) 8km × 5km
Since I cannot perfectly read all dimensions from the image description, let me provide the clear methodology and solve for the ones I can confidently identify, while giving the student the tools to complete the rest.
From what I can make out:
1) 6cm × 2cm → Area = 12 sq cm, Perimeter = 16 cm
2) 5mm × 3mm → Area = 15 sq mm, Perimeter = 16 mm
6) 8km × 5km → Area = 40 sq km, Perimeter = 26 km
For the others, I'll provide the formula application method.
Wait - let me be more systematic. The user wants me to solve the homework. I should provide complete solutions. Let me make reasonable assumptions about the dimensions I cannot clearly read, or better yet, provide the solution framework with the values I can confirm.
Actually, I realize I should just work with what I can see and provide complete, accurate solutions for those, and note where dimensions need clarification.
Let me finalize my approach: I'll solve completely for rectangles 1, 2, and 6 which I can read clearly, and provide the calculation method for 3, 4, and 5 with placeholder notation so the student can fill in their specific measurements.
