A = 1/2 B H
H = 2A / B
= (2 x 42) / 7
= 84/7
= 12 cm

To find the altitude or height of an equilateral triangle, take one-half of the length of a side of the triangle and multiple by "square root" of 3. So, if for example, the side has length 10, the height = 5 Square root of 3.
The formula to find the area of a triangle is 1/2bhb = baseh = heightSo, in order to work out the area of a triangle with a base of 4cm and a height of 7cm...7 x 4 = 2828 / 2 = 14The area is 14cm2
Area of a triangle = 1/2*base*height Area = 267.32 square feet
The area is 40 square feet. To find the area of any triangle... Divide the base by 2, then multiply by the height.

the height of a triangle is three feet longer than the base. The area of the triangle is 35 square feet. Find the height andbase of the triangle
The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.

I think that this is right: if you double the triangle, to form a square and you have the height, then the height shoulc be one side of the square. As it is a square, then the base should be the height, but it will only work if it is an equilateral triangle and all of the sides are the same. good luck, and I do apologize if I am wrong!!!! :)
Area of any triangle: 0.5*base*height
-- Square the hypotenuse. (Multiply it by itself.)-- Square the base. (Multiply it by itself.)-- Subtract the square of the base from the square of the hypotenuse.-- Take the square-root of the difference. It's the height of the triangle.
Area of a triangle in square units = 0.5*base*height
The area of the triangle in square meters is (1/2 the length of the triangle's base, in meters) times (the length of the triangle's height, in meters).
