Answer: Fourth option is correct.
Explanation:
Since we have given that
Base of triangle = 5.4 cm
Length of triangle = 2 cm
As we know the area of triangle.
Area of triangle is given by
![(1)/(2)* base* height\\\\=(1)/(2)* 5.4* 2\\\\=5.4\ cm^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/oo3mkipfe8nj8xwjnz7k90wdtpkptxv41f.png)
Hence, the area of triangle would be 5.4 cm².
Thus, Fourth option is correct.
