The legs of a right triangle are 12 centimetres and 16 centimeters. what is the length of the hypotenuse? 15 centimeters 17 centimeters 20 centimeters 28 centimeters

The length of the hypotenuse is 20 centimeters.

In order to solve this question, we'll use the Pythagoras formula which will be:

a² + b² = c²

where,

First leg = a = 12 centimeters

Second leg = b = 16 centimeters

Hypothenuse = c = Unknown

It should be noted that the hypothenuse is the longest side and therefore the formula will be:

a² + b² = c²

12² + 16² = c²

144 + 256 = c²

400 = c²

Therefore, c = ✓400

c = 20

Therefore, the length of the hypotenuse is 20 centimeters.
