Step-by-step explanation:
We know that 17cm is the hypotenuse of a right triangle with one side being 15cm.
So from the Pythagorean theorem we know that 17^2 - 15^2 will equal the square of the other side. 289 - 225 = 64 which is 8^2.
Therefore the rectangle has sides of 8 and 15.
Area is 120 cm^2 and perimeter is 46 cm.
