Here is a rectangle ABCD BC is 20cm
DC is 30cm
The length of the rectangle is increased by 10%
The width of the rectangle is increased by 5%
Find the percentage increase in the perimeter of the rectangle

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
