Question

Find the missing dimension of the triangle.Area = 30 mm-6 mmbb=mm

Answer 1

The area of a triangle is:

A= 30mm

h= 6mm

`\begin{gathered} A=(b(h))/(2) \\ \\ 30=\text{ }(b\lparen6\rparen)/(2) \\ \\ 30\text{ \lparen2\rparen = 6b} \\ \\ 60=\text{ 6b} \\ \\ (60)/(6)=\text{ b} \\ \\ 10=\text{ b} \end{gathered}`

The base of the triangle is 10mm
