The area of a triangle is given by the following formula:


A=(bh)/(2),

where b= base, and h=height.

Now, if we multiply b by 1/2, and h by 3, we get:


(b((1)/(2))h(3))/(2)=(3bh)/(2(2))=(3)/(2)(bh)/(2)=(3)/(2)A.

Therefore, if A=124 square units, the new area would be:


(3)/(2)A=(3)/(2)(124u^2)=186u^2.

Answer:


\begin{equation*} 186u^2. \end{equation*}
