Question

If P = 2L + 2B and B = 23.4, what is the value of P when L = 19.2?

A) 85.8
B) 66.0
C) 65.4
D) 42.6

Answer 1

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.

Answer 2

P = 85.2

A) at 85.8 comes closest. Please check for a typo.

Step-by-step explanation:

P = 2L + 2B and B = 23.4

We can rewrite this as P = 2L + 2(23.4), or P = 2L + 46.8

If L = 19.2:

P = 2L + 46.8

P = 2*(19.2) + 46.8

P = 85.2
