4 * 7 = 28
28/2 = 14 sq cm
The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
Area = 0.5*21*28 = 294 square inches
area = ½ × base × height = ½ × 6 units × 13 units = 39 units²
A = leg1leg2/2 = (8)(12)/2 = 48
The hypotenuse is: about 12.81

39 sq. unitsThe area of any right triangle is A = 1/2 (b x h)1/2 (base) multiplied by (height)A right triangle can always be set down so that the legs are the base and the height.So if you know the length of the legs, you can apply the area formula directly.
56 square units
area = ½ × base × height = ½ × 6 units × 13 units = 39 units²
