Please help me! A, b,c, or d?

B

Step-by-step explanation:

total surface area=2 triangles with base 6 and height 4 m +2 rectangles with length 12 m and width 5 m +one rectangle with dimensions 12 m×6 m

=2×1/2 ×6×4+2×12×5+12×6

=24+120+72

=216 m²

C. 216

Step-by-step explanation:

Surface Area is the outside area of a shape

Area of the two triangles are

A = bh

But we don't need to divide the b x h by half because there is another triangle so

A = bh

A = 6 x 4

A = 24

Then the base square is A = bh

A = 6 x 12 = 72

Then the square is A = bh

A = 5 x 12

A = 60 and since there is another square on the other side we add another 60

60 + 60 + 72 + 24 = 216

what is the answer?

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
