you know the area of a triangle is \[\frac{ 1 }{ 2 } b h\] dw:1370581830579:dw as you can see...you have 2 right triangles the hypotenuse is 6...and the bottom side is 6/2 = 3 so now you have 1 side...the hypotenuse...find the other side *which will be your height* using the Pythagorean theorem 3² + b² = 6²

no ..what you get from b = √(6²  3²) will be your height Then you plug THAT into that other equation along with the base length (6) \[\frac{ 1 }{ 2 } (6) (height)\]

well lets see 36  9 = 27 √ 27 = 5.19615242270 that is your height \[\frac{ 1 }{ 2 } (6) (5.19615242270)\] and that comes out to 15.59 would be the area
