RO divides the rectangle into two congruent right triangles.
The area of the one triangle is equal half area of the rectangle.
Calculate the area of rectangle:

The area of right triangle:

Use the Pythagorean theorem to calculate the length of RO:

The formula of an area of this right triangle is:

Therefore we have the equation:

Answer:
1.5
Step-by-step explanation:

What's up? the answer is 1/2
6 sides in which 3 are odd. 1,3,5
3/6 or 1/2 chance of rolling odd
So all you have to do is look at were the number is is it is in the first spot it is in the tenths place value, second spot hundredth and so
