Please help I will give brainliest!! I also need an explanation on how.

  rectangle with sides x, 2x+2

Step-by-step explanation:

The perimeter of the triangle shown is the sum of its side lengths:

  P = (x+3) +(2x+1) +(3x) = 6x +4

A square would have a side length that is 1/4 of this. The side lengths of a square with the same perimeter are ...

  s = (6x +4)/4 = 1.5x +1 . . . . . doesn't match any answer choices

__

A rectangle has a perimeter that is twice the sum of the side lengths:

  P = 2(L + W)

Then the sum of the side lengths would need to be ...

  6x +4 = 2(L +W)

 3x +2 = L + W . . . . . requirement on rectangle with the same perimeter

__

Choice 3:

  The sum of side lengths of this rectangle is (x) +(2x+2) = 3x+2. This matches the perimeter of the triangle.

Choice 4:

  The sum of side lengths of this rectangle is (2x) +(x+1) = 3x +1. This does not match the perimeter of the triangle.

"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.
