<u>Rational Numbers</u>
A rational number is any number that can be expressed as a fraction

for a and b any integer and b different from 0.
As a consequence, any number that cannot be expressed as a fraction or rational number is defined as an Irrational number.
Let's analyze each one of the given options

The first part of the number is indeed a rational number, but the second part is a square root whose result cannot be expressed as a rational, thus the number is not rational

The second part is an exact square root (resulting 4) but the first part is a known irrational number called pi. It's not possible to express pi as a fraction, thus the number is irrational

The square root of 121 is 11. It makes the whole number a sum of a rational number plus an integer, thus the given number is rational

As with the first number, the square root is not exact. The sum of a rational number plus an irrational number gives an irrational number.
Correct option:

1 gallon = 128 oz
2 gallons = 256 oz
256/10 = 25.6 oz

Formula for perimeter: length x 2 + width x 2
70x2 is 140 then subtract it from 180 and you’ll get 40, then you half it and get 20
