The Pythagorean Theorem states that
, where a and b are the legs of a right triangle and c is the hypotenuse of the same triangle.
Anything below 2 would fit into the inequality
Centimeters = inches * 2.54
9 inches is equivalent to 9*2.54 = 22.86 centimeters
Perimeter = the addition of all of the side lengths of the polygon.
The side lengths are 9cm, 6cm, 10cm, 5cm, 4cm, and 4cm.
So the perimeter is the following...
Perimeter = 9 + 6 + 10 + 5 + 4 + 4 = 38cm total
