A poster is 3 inches long. it is 4 times as wide as it is long find the perimeter and area of the poster?
iren [92.7K]
So we know that the width is 12 because 4 x 3 = 12. The formula to find the perimeter is Length + length + width + width. So you would do 3 + 3 + 12 + 12 = 30. Therefore the perimeter is 30 inches

The equation   can be used to determine the number of centimeters, y, in a given number of inches, x. The equation was used to f
Vitek1552 [10]

Answer:

25 Inches

Step-by-step explanation:

Given the table:

\left|\begin{array}{c|c|c|c|c}\text{Number of Inches}&2&10&&40\\\text{Number of Centimeters}&5.08&25.04&63.5&101.6\end{array}\right|

We want to determine the missing value on the table.

Let the missing value be x.

1 inch = 2.54 cm

x inch = 63.5

Expressing the above as a ratio

\dfrac{1}{x}=\dfrac{2.54}{63.5}  \\$Cross Multiply$\\2.54x=63.5\\$Divide both sides by 2.54$\\x=25 \:Inches

Therefore, the missing value is 25.
