The answer is 6. The formula is 1/2 of base times perpendicular height. In the case of a 3:4:5 triangle, there is a right angle between the two shorter sides so they are inherently perpendicluar to each other. So you can either say the base is 3 and the perpendicular height is 4 or the base is 4 and the perpendicular is 3 - either way 1/2 x 3 x 4 = 6. Brian DOWNIE The answer is 6.

Area of Equilateral Triangle A= S2 * (Root 3)/4, where A= Area of the triangle S= Side of the triangle.
Oh, what a happy little question! Yes, it is possible to build a triangle with sides of 3 cm, 4 cm, and 5 cm. This special triangle is called a right triangle, and it follows the Pythagorean theorem where the square of the longest side (5 cm) is equal to the sum of the squares of the other two sides (3 cm and 4 cm). So go ahead and paint that lovely triangle with confidence!
no.
Area of a triangle is 1/2*Base*Height. I believe you can take it from here.
Area of a triangle = 1/2 x (base) x (height) In this situation, the base [b] = height [h] + 10 And the Area = 28 So the 28 = 1/2 x (h + 10) x h The base is 14 cm and the height is 4 cm
