let

a = 16.8 cm

b = 32 cm

c = the hypotenuse of the right triangle, c>0

the area of a right triangle is calculated by the formula: A = (1/2)ab

A = (1/2)*16.8*32

A = 268.8 cm^2

the perimeter of a triangle is: P = a + b + c

lets find c using the Pythagorean Theorem:

c^2 = a^2 + b^2

c^2 = 16.8^2 + 32^2

c = 36.14 cm

the perimeter is:

P = 16.8 + 32 + 36.14

P = 84.94 cm
