you can't unless you measure it.
It is impossible to find the area of a triangle with no height, if the triangle had no height it would not even be a triangle, just a angle.
The height has not been given but the area of the triangle is: 0.5*height*base
If a right triangle has an area of 81 meters an a base of 9 meters its height is: 18 meters.
multiply the base of the triangle by the height then halve the answer.
Use the formula 1/2 the base * the height
Area of a right angle triangle is: 0.5*base*height
Area=1/2(base*height) where either side can be the base or the height in a right triangle.
It is impossible to find the area of a triangle with no height, if the triangle had no height it would not even be a triangle, just a angle.
1/2*base of triangle*height(the perpendicular)=Area of right angled triangle
The height has not been given but the area of the triangle is: 0.5*height*base
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
The area of a right triangle with base of 8 and height of 8 is: 32 square units. The hypotenuse is 11.31 units.
If a right triangle has an area of 81 meters an a base of 9 meters its height is: 18 meters.
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.)
multiply the base of the triangle by the height then halve the answer.
area=(1/2)*base*height
only solids have "lateral area". triangles have "area". the area of a scalene triangle is given by heron's formula. height not needed.
