Step-by-step explanation:
To find the value of 2m² when m = 1.5, first, substitute the value of m into the expression:
2(1.5)²
Next, square the value of 1.5:
2 * (1.5 * 1.5)
Now, calculate the square of 1.5:
2 * (2.25)
Finally, multiply 2 by 2.25:
2 * 2.25 = 4.5
So, 2m², when m = 1.5, is equal to 4.5 square units.
