really need HELP!!! The formula for that area of a triangle is A = 1/2}bh. If the base is 5\sqrt 3 and the height is \sqrt {18} , what is the area of this triangle in radical form?

    \[Area = \frac{1}{2} \times \frac{5}{\sqrt{3}} \times \sqrt{18} = \frac{1}{2} \times 5 \times \sqrt{\frac{18}{3}}\] simplify the fraction inside the radical for the answer.

    @campbell_st Perhaps the poster meant this: \(A = \dfrac{bh}{2} \) \(A = \dfrac{5 \sqrt{3} \times \sqrt{18} }{2} \)

    well if thats the case its \[Area = \frac{5 \times \sqrt{3 \times 18}}{2}\]

    \(Area = \large \frac{5* \sqrt{54}}{2} = \frac{5* \sqrt{9*6}}{2}=\frac{15\sqrt{6}}{2} \) If you would not like the sqrt in your answer thennn \( \sqrt{6}\) is approximately 2.45 sooo \( Area = \large \frac{15*2.45}{2}\)

    nooooooo Radical form is what I showed above \( Area = \large \frac{15\sqrt{6}}{2}\)
