A3 mm5 mmA. 12 mm²B. 18 mm²C. 24 mm²D. 30 mm²4 mmThe area of AABD isD12.4 mm8 mmB

Answer 1

The area of a triangle is given by:

`A=(1)/(2)bh`

In this case the base is 8 mm and the height is 3 mm, then we have:

`\begin{gathered} A=(1)/(2)(8)(3) \\ A=12 \end{gathered}`

Therefore, the area is 12 mm²
