Explanation:
The scale factor is a number that is used to dilate or reduce a geometric figure. It is the ratio of the length of a side of the dilated figure to the corresponding side of the original figure.

Question 1:
Length = 4 units
Length of enlarge square = scale factor × length
= 1.5 × 4
= 6 units
Now,
The perimeter of the enlarged square is: 4 × enlarged length
= 4 × 6
= 24 units
Question 2:
Since the two triangles are similar, the ratio of their corresponding sides is equal.

Solving for x, we get:


Question 3:
Since the two triangles are similar, the ratio of their corresponding sides is equal.

Solving for x, we get:


Question 4:
The scale factor is the ratio of the corresponding sides of the two similar figures.
