Answer:

64a² - 25

Step-by-step explanation:

Given

$l = 8a + 5\\w = 8a - 5$

Asked

$Area_{rectangle} = ?$

Formula

$Area_{rectangle} = lw$

Solution

$Area_{rectangle} = lw$

$Area_{rectangle} = (8a + 5) (8a - 5)$

$Area_{rectangle} = 64a^{2} + 40a - 40a - 25$

$Area_{rectangle} = 64a^{2} - 25$

Formula

$Area_{rectangle} = 64a^{2} - 25$

The area of the rectangular shoebox is 64a² - 25.

I hope it helps! Thank you! ❤️

Answer:

8a^2-25

Step-by-step explanation:

(8a+5)(8a-5)=A

8a^2+40a-40a-25=A

cancel out 40a-40a

8a^2-25=A
