1) Norman uses 12.9 km² of land for his sunflowers.
- Calculation: Area = length × width = 3 km × 4.3 km = 12.9 km².
2) Jo anna needs 1.82 m² of fertilizer.
- Calculation: Area of triangle = (base × height) / 2 = (1.4 m × 2.6 m) / 2 = 3.64 m² / 2 = 1.82 m².
3) Sue will need 6 in² of fabric.
- Calculation: Area of triangle = (base × height) / 2 = (2 in × 6 in) / 2 = 12 in² / 2 = 6 in².
4) Allyson will jog 660 yards.
- Calculation: Perimeter of rectangle = 2 × (length + width) = 2 × (100 yd + 65 yd) = 2 × 165 yd = 330 yd.
- Distance for two laps = 2 × 330 yd = 660 yd.
5) The farmer will need 700 feet of fencing.
- Calculation: Perimeter of rectangle = 2 × (length + width) = 2 × (200 ft + 150 ft) = 2 × 350 ft = 700 ft.
6) The area of the brownies is 35 cm².
- Calculation: Area = length × width = 7 cm × 5 cm = 35 cm².
