Answer 1

To find the area, A, of a triangle, the formula is

`\begin{gathered} A=(1)/(2)bh \\ A\text{ is the area } \\ b\text{ is the base} \\ h\text{ is the height} \end{gathered}`

Given that;

`\begin{gathered} A=84\text{ m}^2 \\ h=12\text{ m} \end{gathered}`

Substitute the values of the variables into the formula above

`\begin{gathered} A=(1)/(2)bh \\ 84=(1)/(2)* b*12 \\ 84=6b \\ b=(84)/(6) \\ b=14\text{ m} \end{gathered}`

Hence, the measure of the base, b is 14 m
