Question

what is the perimeter of a rectangle measuring 47 inches by 78 inches? you do not need to include the unit measurement or unit type. only the numerical answer is necessary. round to the nearest tenth if necessary. review the linked section of the prealgebra textbook for problem help

Explanation:

Step1: Recall the perimeter formula

The formula for the perimeter \(P\) of a rectangle is \(P = 2(l + w)\), where \(l\) is the length and \(w\) is the width.

Step2: Substitute the values

Given \(l = 78\) and \(w = 47\), substitute into the formula: \(P=2(78 + 47)\).
First, calculate the sum inside the parentheses: \(78+47 = 125\).
Then, multiply by 2: \(P = 2\times125\).

Step3: Calculate the result

\(2\times125=250\).

Answer:

250
