Question

at school, akihiro draws a model of the flag of japan in the coordinate plane. what is the perimeter of the flag akihiro draws?

Explanation:

Step1: Identify length and width

Assume the vertices of the rectangle - shaped flag model. If we consider the coordinates of the vertices, we can find the length and width. Let's say by counting the grid - squares, the length \(l\) of the rectangle is 8 units and the width \(w\) is 4 units.

Step2: Use perimeter formula

The formula for the perimeter \(P\) of a rectangle is \(P = 2(l + w)\). Substitute \(l = 8\) and \(w = 4\) into the formula: \(P=2(8 + 4)\).

Step3: Calculate the perimeter

First, add the values inside the parentheses: \(8+4 = 12\). Then multiply by 2: \(2\times12=24\).

Answer:

B. 24 units
