The area of a right-angle triangle is half of the area of a rectangle 8cm x 4cm. Find the rectangle area and divide by half to find the area of the right-angle triangle.
Therefore: 8 x 4 / 2 = 16cm2

The above answer assumes that the two given lengths are the shorter legs of the triangle. It is, however, possible that these are the hypotenuse and one leg. In that case, the second leg is 4*sqrt(2) cm and the area of the triangle is
4 * 4*sqrt(2) / 2 = 8*sqrt(2) = 11.31 cm2.

What is the area of a triangle 4cm by 8cm?
To find the area of a triangle, you can use the formula: Area = 0.5 * base * height. In this case, the base is 8cm and the height is 4cm. Plugging these values into the formula, the area would be 0.5 * 8cm * 4cm = 16 square centimeters.

What is a triangle with 6cm 8cm and 4cm?
The area of the triangle with these sides is found by Heron's formula, which states that: semiperimeter = (a + b + c) / 2 Area = √(s(s - a)(s - b)(s - c)) Then: semiperimeter = (6 + 8 + 4) / 2 cm = 9 cm Area = √(9(9 - 8)(9 - 6)(9 - 4)) cm² ≈ 11.6 cm²
