Answer: 96 units

Step-by-step explanation:

3 by 4 Right Triangles: (3*4)/2 for <em>each </em>triangle, so 2((3*4)/2)=12  units for both two triangles.

Middle Rectangles:<em> </em>Since all of the 3 rectangles have the same height, we can add together the widths to get (3+4+5)*7=12*7=84 units.

Add them together: 84+12=96 units

I hope it helps!

lesantik [10]

Answer:

Justice lived in Germany for 15 months and he lived in Holland for 9 months.

Step-by-step explanation:

1. You must make a system of equations:

\left \{ {{x+y=24} \atop {120x+220y=3780}} \right.

Where x is the number on months he lived in Germany and y is the number on months he lived in Holland.

2. You can solve this system of equations by using the Elimination Method. If you multiply the first equation by -120, you can cancel the variable x when you add both equations, and then you can calculate y. When you obtain the value of y, you can substitute it into one of the original equations and solve for x. Then:

 \left \{ {{-120x-120=-2880} \atop {120x+220y=3780}} \right.

100y=900\\y=9

x+y=24\\x+9=24\\x=15
