The hypotenuse of a right-angled triangle is 5 cm. One of the legs is 4 cm

The hypotenuse of a right-angled triangle is 5 cm. One of the legs is 4 cm. The other leg is 1 cm shorter than the first leg. Find the perimeter of the triangle.

Let’s calculate how many centimeters the value of the length of the other leg of this right-angled triangle will equal, if we know, according to the conditions from this task, that the length of the first leg exceeds it by one centimeter:

4 – 1 = 3.

Let’s calculate how many centimeters the value of the perimeter of this geometric figure will equal, if it is known, according to the conditions from this task, that the length of the third side is five centimeters:

3 + 4 + 5 = 12.

Answer: The perimeter is 12 cm.
