Question

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

Explanation:

Step1: Determine the length and width

Assume each tile has a side - length of 1 unit. The length \(l = 6\) units and the width \(w=3\) units.

Step2: Use the perimeter formula for a rectangle

The formula for the perimeter of a rectangle is \(P = 2(l + w)\). Substitute \(l = 6\) and \(w = 3\) into the formula: \(P=2(6 + 3)\).

Step3: Calculate the value

First, calculate the sum inside the parentheses: \(6+3 = 9\). Then multiply by 2: \(P=2\times9=18\).

Answer:

18
