Check the picture below.
the lateral area, namely the area of the sides, as you see in the picture, is really just the area of 6 rectangles.
front and back, two rectangles of 5x25,

Answer:
f(m) = -9
Step-by-step explanation:
We replace m with 5 in the function.
f(m) = 1 - 4(m/2) becomes f(5) = 1 - 4(5/2)
then we solve the numbers in the parenthesis first
= 1 - 4 (5/2)
= 1 - 4 (2.5)
= 1 - 10
= -9
Answer: 243 people
Step-by-step explanation:
ration of 7 children to every 2 caretakers, and there are 189 children. So, since ratio of children is 7, divide 189 by 7 and get 54. Then multiply by 2 since that is the ratio for caretakers to get 54 caretakers. You can check these numbers by putting in the calculator 189/54, it simplifies to 7/2. Add 54 and 189 to get total number of people which is 243.
