1. which statement about the figure below is true?

Explanation:

Step1: Calculate the area of the large rectangle

The formula for the area of a rectangle is \(A = length\times width\). The length of the large rectangle is \(9m\) and the width is \(4m\). So the area \(A_1=9\times4 = 36m^{2}\).

Step2: Calculate the area of the small rectangle (window)

The length of the small rectangle is \(1m\) and the width is \(4 - 3=1m\). Using the area formula \(A = length\times width\), we get \(A_2 = 1\times1=1m^{2}\).

Step3: Calculate the area of the wall

Subtract the area of the small rectangle from the area of the large rectangle. \(A=A_1 - A_2\). So \(A = 36- 10=26m^{2}\).

Answer:

A. \(26m^{2}\)
