Question

1. what is the perimeter of a rectangle that has 6 tiles across and 3 tiles down? 24 12 9 18

Explanation:

Step1: Determine the length and width

Assume the side - length of each tile is \(1\). The length \(l = 6\) (since there are 6 tiles across) and the width \(w=3\) (since there are 3 tiles down).

Step2: Use the perimeter formula

The formula for the perimeter of a rectangle is \(P = 2(l + w)\). Substitute \(l = 6\) and \(w = 3\) into the formula: \(P=2(6 + 3)\).
First, calculate the sum inside the parentheses: \(6+3=9\). Then multiply by 2: \(P = 2\times9\).

Answer:

\(18\)
