Answer:
The surface area of the lower rectangle is 20cm x 4cm= 80 square cm
the surface area of the two triangles is 12 square centimetres
the surface area of one of the top rectangular faces is 20×5= 100 square centimetres
the surface area of the other is 20×3= 60 square centimetres

Step-by-step explanation:
Given: 60% of the boys play baseball and 24% of the boys play baseball and football in Seaton Park School
To find: percentage of those that play baseball also play football
Solution:
Let B denotes boys who play baseball and F denotes boys who play football.
![P(B)=60\%](https://tex.z-dn.net/?f=P%28B%29%3D60%5C%25)
![P(F\cap B)=24\%](https://tex.z-dn.net/?f=P%28F%5Ccap%20B%29%3D24%5C%25)
Percentage of those that play baseball also play football = ![P\left ( F|B \right )=\frac{P(F\cap B)}{P(B)}=\frac{24}{60}=\frac{2}{5}=0.4\%](https://tex.z-dn.net/?f=P%5Cleft%20%28%20F%7CB%20%5Cright%20%29%3D%5Cfrac%7BP%28F%5Ccap%20B%29%7D%7BP%28B%29%7D%3D%5Cfrac%7B24%7D%7B60%7D%3D%5Cfrac%7B2%7D%7B5%7D%3D0.4%5C%25)
