March 26, 2021 | education
| 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.
