Answer:
PART A:
The length of each side of the square is 4a - 3
PART B:
The dimension of the rectangle is:
(3a - 5b)(3a + 5b)
Explanation:
PART A:
Given that the area of the square is:
[tex]16a^2-24a+9[/tex]
Factorizing this, we have:
[tex](4a-3)^2[/tex]
Therefore, the length of each side is:
[tex]4a-3[/tex]
PART B:
Given that the area of a rectangle is:
[tex]9a^2-25b^2[/tex]
Factorizing this, we have:
[tex](3a-5b)(3a+5b)[/tex]
