Apply pythagorean theorem.

c^2 = a^2 + b^2

a^2 = c^2 - b^2

a = √(c^2 - b^2)

a = √[(6.5)^2 - (2.5)^2] = √(36) = 6

solving the perimeter of the right- angles triangle..

P = a + b + c

P = 6.5 cm + 6 cm + 2.5 cm = 15 cm answer//

A right-angled triangle

with a hypotenuse of 6.5 cm and another side of 2.5 cm:

x^2 = 6.5^2 - 2.5^2

x = sqrt (9*4) = 6

The perimeter = 15 cm
