What’s the formula??

Answer:
Area = 78
Perimeter = 42
Step-by-step explanation:
[tex]Area_{parallelogram} = base * height[/tex]
[tex]Perimeter_{parallelogram} = 2 * width + 2 * length = 2 * (width + length)[/tex]
[tex]width = 8[/tex]
[tex]length = 13[/tex]
[tex]base = 13[/tex]
[tex]height = 6[/tex]
[tex]Area_{parallelogram} = 13 * 6 = 78[/tex]
[tex]Perimeter_{parallelogram} = 2 * (13 + 8) = 2 * 21 = 42[/tex]
