Answer:
99 [tex]m^{2}[/tex]
Step-by-step explanation:
First, figure out the area of the left rectangle which has a width of 4 m and a length of 12. The area of the left rectangle is A = l*w = 12 * 4 = 48 [tex]m^{2}[/tex]. The middle rectangle has a width of 5 m and a length of 3 m, so the area is A = l*w = 3 * 5 = 15 [tex]m^{2}[/tex]. The right rectangle has a with of 3 m and a length of 12 m, so the area is A = l*w = 12 * 3 = 36 [tex]m^{2}[/tex]. Finally, we add the areas together to get the final answer of 48 [tex]m^{2}[/tex] + 15 [tex]m^{2}[/tex] + 36 [tex]m^{2}[/tex] = 99 [tex]m^{2}[/tex].
