The area of a right-angled triangle is 16 cm2. How long can its sides be, forming a right angle.

The area of a right triangle is the product of 1/2 of the area of the rectangle, so the total area will be:

16 / 1/2 = 16 * 2/1 = 32 cm2

Let’s say that one side of the rectangle is 2 cm, then the second will be:

32/2 = 16 cm.

If the first side is 4 cm, then the second will be equal to:

32/4 = 8 cm.

Answer: The sides forming a right angle can be 2 and 16 cm long, as well as 4 and 8 cm.
