Use the scale factor to find the area of the enlarged figure. Explain your steps.

A small rectangle has a length of 8 and width of 4. A large rectangle has a length of 25.6 and width of a.

12.8 units

Step-by-step explanation:

25.6/8 = a/4

a = 4 * 25.6/8

a = 12.8

Answer: 327.68

Step-by-step explanation:The scale factor of the enlargement is 3.2. Square the scale factor to get 10.24. Find the area of the original figure, which is 32. Multiply 32 and 10.24 to get the area of the enlarged figure, which is 327.68.
