Question

the area of a square poster is 26 in.². find the length of one side of the poster to the nearest tenth of an inch. (round to the nearest tenth as needed.) the length of one side of the poster is \boxed{} in.

Explanation:

Step1: Recall area of square formula

The area \( A \) of a square is given by \( A = s^2 \), where \( s \) is the side length. We know \( A = 26 \) in², so we need to solve for \( s \): \( s=\sqrt{A} \).

Step2: Calculate the square root

Substitute \( A = 26 \) into the formula: \( s=\sqrt{26} \). Calculate \( \sqrt{26}\approx5.1 \) (rounded to the nearest tenth).

Answer:

\( 5.1 \)
