Answer 3

which one do you want to do?

Answer 4

We can start on the first one if you don't mind:) I just don't understand them.

Answer 5

Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number.

lateral area is the "side area" , which is the area not including the "top or bottom"
That is not very clear, but we we assume the top and bottom are the triangles

and that means the "sides" are the 3 rectangles.

Answer 6

The first step to doing this is find the length and width of each side
can you say what the length and width of the "bottom rectangle" is ?

Answer 7

23 and 9

Answer 8

and the area of a rectangle is length * width
so the area of the bottom side is 23*9

Answer 9

Which sides do you do this to?

Answer 10

we are finding the area of the sides that are "rectangles"
this is the bottom side of the prism
