The legs of a right-angled triangle are 2 cm and 4 cm. Find its hypotenuse and area.

Let us determine with the help of how many square centimeters it will be possible to represent the area of this right-angled triangle, when from the condition of the task we know that its legs are two and four centimeters, respectively:

2 * 4 * 1/2 = 4.

Answer: Under such initial conditions, the area of the triangle will be 4 cm2.

Let’s determine how many centimeters it will be possible to represent the length of the hypotenuse of this triangle:

√ (4 ^ 2 + 2 ^ 2) = √ (16 + 4) = √20 = 2√5.

Answer: 2√5 centimeters.
