It is irrational, as it's not a number that can be divided into a whole number by another whole number.

It is irrational because an irrational number has endless non-repeating digits to the right of the decimal point.

Answer:

90 m²

Step-by-step explanation:

The given linear dimensions have the ratio ...

red/blue = (6 m)/(4 m) = 3/2

The ratio of areas is the square of the ratio of the linear dimensions:

(red area)/(blue area) = (3/2)²

S = (blue area)(9/4) = (40 m²)(9/4)

S = 90 m²
