There is no right triangle on the right! (Ignore the length of the hypotenuse of a right triangle.) if you have the length of the two legs (base and the upright side): (base x upright) ÷ 2 = area of the right angle triangle.
A = 1/2(base)(height)
Right triangle square rectangles
A right triangle is easy, simply multiply the two sides and divide by two. A non-right triangle is a bit more of a challenge. You have to make it a right triangle by adding a right triangle to it. Calculate and then subtract the area of what you had to add.
The given dimensions are not compliant for the construction of a right angle triangle but the area of any triangle is: 0.5*base*height
Area of a right angle triangle is: 0.5*base*height
area=(1/2)*base*height

The given dimensions are not compliant for the construction of a right angle triangle but the area of any triangle is: 0.5*base*height
The area of a triangle is one half base times height. In the case of a right triangle, the base is one leg and the height is the other leg. (The two legs being separated by the right angle.)
The right-angle triangle measures 28cm by 35cm. Such a triangle is half of a rectangle.Therefore 28 x 35 = 980cm2 is the area of a rectangle.980 / 2 = 490cm2 will give the area of the triangle (which is 490cm2).
1/2bh trick-1/228=8cm2
divide the footiing into two right angle triangles & a rectangle . calculate the area of rt < triangle & rectangle respectively,. the area so obtained when multiplied by length of footing gives quantity of concrete.
If its a right angle triangle then its side lengths could be 3, 4 and 5
