Given:

Base = 15 cm

Hypotenuse = 17 cm

Formula Used:

Area of a right triangle = (1/2) × base × height

Pythagorean Theorem: a2 + b2 = c2

Calculation:

Using Pythagorean Theorem to find the height:

Base (a) = 15 cm

Hypotenuse (c) = 17 cm

Height (b) = ?

⇒ 152 + b2 = 172

⇒ 225 + b2 = 289

⇒ b2 = 289 - 225

⇒ b2 = 64

⇒ b = 8 cm

Now, calculate the area of the right triangle:

Area = (1/2) × base × height

⇒ Area = (1/2) × 15 cm × 8 cm

⇒ Area = (1/2) × 120 cm2

⇒ Area = 60 cm2

The area of the right triangle is 60 cm2.
