2.

If one rectangle's dimensions are doubled (k=2) what is the effect on the area

1/2

4.

The triangles are similar, find the area of the smaller triangle (use the scale factor in previous question)

347 * (1/4)² = 21.68 m²

347 * (1/2) = 173.5 m²0

347 * (1/4) = 86.75 m²

347 * (1/3)² = 38.5 m²
