**Ms. Sue**, Tuesday, August 9, 2011 at 7:08pmFirst, find the length of the third side by using the Pythagorean Theorem.

a^2 + b^2 = c^2

16^2 + b^2 = 34^2

256 + b^2 = 1,156

b^2 = 1,156 - 256

b^2 = 900

b = 30 inches

The perimeter is the length of all three sides added together.

The area is found with this formula:

A = bh/2

If you post your answers here, I'll check them for you.

**Reiny**, Tuesday, August 9, 2011 at 7:33pmthe longest side in a right-angled triangle is the hypotenuse, let the missing side be x

x^2 + 16^2 = 34^2

x^2 = 900

x = 30

perimeter = sum of the three sides

area = (1/2)(16)(30) = ....
