Question

look at this square. find the value of w.
perimeter = 20 yards
w = yards

Explanation:

Step1: Recall square perimeter formula

A square has 4 equal sides. The perimeter \( P \) of a square is given by \( P = 4 \times \text{side length} \). Here, the side length is \( w \), so \( P = 4w \).

Step2: Substitute perimeter value

We know the perimeter \( P = 20 \) yards. Substitute into the formula: \( 20 = 4w \).

Step3: Solve for \( w \)

Divide both sides by 4: \( w = \frac{20}{4} = 5 \).
