Whats the answer to this problem?

81m²

Step-by-step explanation:

The area of the rectangular part is given by length × width;

i.e 6m × 10m = 60m²

The area of the triangular part is given by × base × height

So it will be × 6m × 7m = 21m²

Total area = Area of the composite figure = 60m² + 21m² = 81m²

"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.
