Answer:
In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line (or alternatively, a quantity that can be represented as an infinite decimal expansion).
Since a rectangle has 4 side than 2 sides that have the width of 10 would be 20 and 20 minus 90 equals 70 and half of 70 is 35 so the length of the other 2 sides would be 35.35+35+10+10=90
No, because all numbers that end in zero are able to be divided by sometimes 2, and always 5. And 0 doesn't count as a prime number.
