Knowing just the length of the base you can not work out the area. You need the height and the base or the length of the hypotenuse in order to work out the area.
1/2*base of triangle*height(the perpendicular)=Area of right angled triangle
how to find the perimeter of a right angled triangle using the area
The area of a 12cm by 5cm right-angled triangle is: 42 cm2
multiply the base of the triangle by the height then halve the answer.
the area of a right angled triangle is 30sqcm one leg is 6cm what is the length of the other one
The area of a right-angled triangle with base 8 cm and hypotenuse 10 cm is: 24 cm2
A right triangle is easy, simply multiply the two sides and divide by two
area = base * height / 2;
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.
Area of a right triangle = 1/2 base x height Area = 1/2 10x6 Area = 30
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.)
56 cm2 * * * * * Only if these are the shorter legs of a right angled triangle and there is no justification for making that assumption. Two sides of a triangle are not sufficient to determine its area.
