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
4 * 7 = 28 28/2 = 14 sq cm
A = leg1leg2/2 = (8)(12)/2 = 48
The hypotenuse is: about 12.81

The area is 272 square inches.32*17/2=272
Area = 0.5*21*28 = 294 square inches
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
Lets work it out:- If the legs are 12 and 16 inches, then a rectangle of that size would be 192 square inches in area. As the the diagonal of the rectangle makes two equal triangles (of legs 12 and 16 inches), the area of one of these is half the area of the triangle - 192/2 = 96 square inches.
