For the bottom, to find the top side of the triangle, 10-4, as seen from the top and bottom sides of the rectangle. So 6.

To find the left side of triangle, subtract 12 from 8. 12 from the left and 8 from the rectangle. This gives you 4.

Now that we have 6 and 4, we can find the area:

A= ab/2

A= (6*4)/2

A=24/2

A=12 mm^2

Answer:

(2a - 3x - 3y)(2a + 3x + 3y)

Step-by-step explanation:

Hi there !

use formula

a² - b² = (a - b)(a + b)

a = 2a

b = 3(x + y)

4a² - 9(x+y)² =

= [2a - 3(x + y)][2a + 3(x + y)]

= (2a - 3x - 3y)(2a + 3x + 3y)

Good luck !
