The area of a right-angled triangle is 54 cm², and one of the sides forming a right angle is 18 cm. Find the second side of this corner.
The area of a right-angled triangle is half the product of the legs: S = 0.5ab. The unknown leg can be found by dividing twice the area by the length of the other leg: b = 2S / a. According to the condition of the problem, the area is 54 cm2, one of the legs is 18 cm, we find the second leg: 2 * 54/18 = 6 cm.
