Final answer:
By substituting the given values into the equation P = 2L + 2B, we arrive at a calculated P value of 85.2. The provided multiple-choice options do not include this precise value, but option A) 85.8 is the closest.
Step-by-step explanation:
To find the value of P when L = 19.2 and B = 23.4, we start by plugging these values into the provided formula P = 2L + 2B. By substituting the given values, the equation becomes P = 2(19.2) + 2(23.4).
Let's calculate each term separately:
- 2L = 2(19.2) = 38.4
- 2B = 2(23.4) = 46.8
Now add these values together to find P:
P = 38.4 + 46.8 = 85.2
Therefore, the value of P is 85.2, which is not listed in the options provided, indicating there may have been a mistake in the options or in my calculations. However, based on the calculations, the closest option would be Answer A) 85.8, assuming a small rounding error.
