Question

look at this square. find the value of t.
perimeter = 72 millimeters
t = millimeters

Explanation:

Step1: Recall square perimeter formula

A square has 4 equal sides, so perimeter \( P = 4 \times \text{side length} \). Here, side length is \( t \), so \( P = 4t \).

Step2: Substitute perimeter value

We know \( P = 72 \) mm, so \( 4t = 72 \).

Step3: Solve for \( t \)

Divide both sides by 4: \( t = \frac{72}{4} = 18 \).

Answer:

18
