Question

find the perimeter.
write your answer as a fraction or as a whole or mixed number.
$2\frac{1}{4}$ yd
$2\frac{1}{4}$ yd
$2\frac{1}{4}$ yd
$2\frac{1}{4}$ yd
yards

Explanation:

Step1: Recall the perimeter formula for a square

The perimeter \( P \) of a square is given by \( P = 4\times s \), where \( s \) is the length of one side.

Step2: Identify the side length

The side length \( s \) of the square is \( 2\frac{1}{4} \) yards. First, convert the mixed number to an improper fraction: \( 2\frac{1}{4}=\frac{2\times4 + 1}{4}=\frac{9}{4} \) yards.

Step3: Calculate the perimeter

Using the perimeter formula, \( P = 4\times\frac{9}{4} \). The 4 in the numerator and denominator cancels out, leaving \( P = 9 \) yards.

Answer:

$9$
