Question

Find the area of the triangle. Express the answer in simplest form.
(picture attached)

Answer 1

base(height) / 2

Answer 2

A=[1/2 base \times height\]
A= \[1/2 * \sqrt{20} * \sqrt{5}\]

Answer 3

That was supposed to be a 15. But your answer should be 8.660

Answer 4

Use the equation.

Answer 5

If you do it the same way I did it, you get 8.660. \[5\sqrt{3}= 8.660\]

Answer 6

C. 5√(3)
--------------
A = (1/2) b h
A = (1/2) sqrt(20) * sqrt(15)
A = (1/2) * 2√5 * √(5*3)
A = √5 * √(5*3)
A = √5 * √5 * √3
A = 5 √3
