Which of the following formulas, when evaluated using rational values for the variables, will result in an irrational number?
a)the formula for the area of a circle
b)the formula for the area of a trapezoid
c)the formula for the area of a triangle
d)the formula for the area of a rectangle

a) The formula for the area of a circle  

Step-by-step explanation:

The formula for the area of a circle is  

A = πr²

π is an irrational number and, no matter what value you use for r, the area will be an irrational number,

b) is wrong. A = ½(a + b)h.  

c) is wrong. A = ½bh.

d) is wrong. A = bh.

All measurements are rational numbers, so the areas will be rational numbers.

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
