The legs of a right-angled triangle are 8 and 15 cm. Write the hypotenuse and the area of the triangle.

Let us find out what the length of the hypotenuse will equal if from the condition of our problem it is precisely known that the legs in the indicated triangle have lengths equal to 8 and 15 centimeters, respectively:
√ (82 + 152) = √ (64 + 225) = √289 = 17.
Answer: The length of the hypotenuse will be 17 centimeters.

Let us find out what the area of such a triangle will be equal to, for which we use the well-known formula (the area is equal to half the product of the legs):
1/2 * 8 * 15 = 60.
Answer: The area of the figure will be 60 cm2.
