Both of the problems are have parallelograms. To find the area of parallelograms, you can use the formula
. For the first question, we can then replace b with 8.9 and h with 5.3. We can then multiply them both, and we get 47.17. To find the area, we can multiply both sides by 2 and add then together. Your answers will be:
3) Area: 47.17 mm
Perimeter: 29.52 mm
Type: Parallelogram
6) Area: 21.85 cm
Perimeter: 20 cm
Type: Parallelogram
