Answer:

area: [tex]\sf 4a^4b^2[/tex] || perimeter: [tex]\sf 8a^3b+4ab[/tex]

Step-by-step explanation:

perimeter = sum of all sides

perimeter:

[tex]\sf 2a^3b + 6a^3 b + 4ab[/tex]

[tex]\sf 8a^3b+4ab[/tex]

area of triangle = [tex]\sf \frac{1}{2} *base * height[/tex]

[tex]\sf \frac{1}{2} *4ab* 2a^3 b[/tex]

[tex]\sf \frac{1}{2}\cdot \:8ab^2a^3[/tex]

[tex]\sf 4a^4b^2[/tex]
