First, 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.
the 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) = ....
Should have checked first.
