Area of a triangle. Find the exact area of a triangle with a base of (radical symbol) 30 meters and a height of (radical symbol) 6 meters. The radical symbol is like the square root symbol.

A=(1/2)(b)(h)
A= (1/2)(square root of 30)(square root of 6)
A= (1/2)(square root of 180)
A= (1/2)(square root of 36*5)
A= (1/2)(square root of 36)(square root of 5)
A=(1/2)(6)(square root of 5)
A= 3

Area of a triangle =
= 1/2 · base · height
= 1/2 · â30 · â6
= 1/2 · â(30·6)
= 1/2 · â180
(want to simplify â180: )
= 1/2 · â(36·5)
= 1/2 · â36 · â5
= 1/2 · 6 · â5
= 3·â5 m²
Hope this helps.

Radical is square root. On Teh Intawebs, you can type in "sqrt" and we'll all know what you mean.
Area of a triangle is (1/2)*b*h.
So the area would be
A = (1/2)*sqrt30*sqrt6 = (1/2)*sqrt180 = (1/2)*36*sqrt5 = 18sqrt5

Area of a triangle formula
a = 1/2 bh
a = 1/2(â30)(â6)
a = 1/2(â180)
a = â180 / 2
a = 13.41640787 / 2
a = 6.708203933

Sqrt(6*30)/2 =sqrt(180)/2=6*sqrt(5)/2=3*sqrt(5)
