Answer:
120 m^2
Step-by-step explanation:
[tex]A_1 = l * w = 9 * 5 = 45\ m^2[/tex]
[tex]A_2 = 2 * \frac{b*h}{2} = 2 * \frac{3*4}{2} = 3*4 = 12\ m^2[/tex]
[tex]A_3 = l * h = 9 * 3 = 27\ m^2[/tex]
[tex]A_4 = l * w = 9 * 4 = 36\ m^2[/tex]
[tex]A = A_1 + A_2 + A_3 + A_4 = 45 + 12 + 27 + 36 = 120\ m^2[/tex]
