We are asked to find the area of a triangle and the area of a parallelogram. The area of a triangle can be expressed by the formula
![A= \frac{1}{2} bh](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7D%20bh)
. Similarly, the area of a parallelogram can be found using the formula
![A=bh](https://tex.z-dn.net/?f=A%3Dbh)
. In both formulas,
![b=base](https://tex.z-dn.net/?f=b%3Dbase)
and
![h=height](https://tex.z-dn.net/?f=h%3Dheight)
.
Area of a Triangle:Formula:
![A= \frac{1}{2} bh](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7D%20bh)
![b=6m^3n^4](https://tex.z-dn.net/?f=b%3D6m%5E3n%5E4)
![h=5n](https://tex.z-dn.net/?f=h%3D5n)
Plug them in -
![A= \frac{1}{2}(6m^3n^4)(5n)](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7D%286m%5E3n%5E4%29%285n%29)
Multiply -
Parallelogram:
Formula:
![A=bh](https://tex.z-dn.net/?f=A%3Dbh)
![b=6a^4b^2](https://tex.z-dn.net/?f=b%3D6a%5E4b%5E2)
![h=3a^3b^2](https://tex.z-dn.net/?f=h%3D3a%5E3b%5E2)
Plug values in -
![A=(6a^4b^2)(3a^3b^2)\Rightarrow \boxed{A=18a^7b^4}](https://tex.z-dn.net/?f=A%3D%286a%5E4b%5E2%29%283a%5E3b%5E2%29%5CRightarrow%20%5Cboxed%7BA%3D18a%5E7b%5E4%7D)
