This is a prism. The surface area is:
S=2 Ab+Al
Area of the base: Ab=(14 cm)(7 cm)+(14 cm-7 cm)(7 cm)
Ab=98 cm^2+(7 cm)(7 cm)
Ab=98 cm^2+49 cm^2
Ab=147 cm^2
Lateral area: Al=Pb h
Perimeter of the base: Pb=14 cm+14 cm+7 cm+7 cm+(14 cm-7 cm)+7 cm
Pb=14 cm+14 cm+7 cm+7 cm+14 cm-7 cm+7 cm
Pb=3(14 cm)+2(7 cm)
Pb=42 cm+14 cm
Pb=56 cm
Height of the prism: h=5 cm
Al=Pb h = (56 cm)(5 cm)
Al=280 cm^2
S=2 Ab+Al
S=2(147 cm^2)+280 cm^2
S=294 cm^2+280 cm^2
S=574 cm^2

Answer:
342.5
Step-by-step explanation:
Take 55 and multiply it by 3.5
Then multiply 60 by 2.5
Then add those two numbers that you come up with and add them together.
Answer:
A)
Step-by-step explanation:
Order the set first
27, 28, 35, 37, 43, 47
Median now is: 36 (which is the mean between 35 and 37, the two central numbers )
If you add A) 35,50 then you will still have to compute the mean between 35 and 37 in order to find the median, because you have:
27,28,35,35,37,43,47,50
