Hey in melo30's twin .the answer is D.8
Answer:
360 people out of 1200 are likely to have red hair.
Step-by-step explanation:
So I just saw that 100 x 120 equals 1200. So I just need to multiply 3 x 120 and I got 360. I think this is how to solve?
Answer:
The first step that we are going to do is to solve the area of the top rectangle. We are given a width of 15 cm and a length of 25 cm so we can just multiply them against each other to get the area.



The second side that we are going to solve for is the bottom rectangle. We are given a width of 12 cm and a length of 25 cm so lets just multiply them against each other to get the area.



The next area that we are going to determine is the back rectangle which has a width of 9 cm and a length of 25 cm so lets just multiply them against each other to get the area.



The final area that we have to determine are the side triangles. After determining the area of one triangle we will have to multiply it by 2 to get the area for both of the triangles. We are given a base of 12 cm and a height of 9 cm so lets just use the formula to find the area.



Multiply it by two to get the area for both of the triangles.


Finally, we are onto the last part which is to add up all of the areas and get the surface area after we combine everything.


Therefore, our final answer is option B, 1008 
Hope this helps!
