Answer:
22.44 cm^2
Step-by-step explanation:
There's four triangles and one square so lets start with the triangles.
2.24×3÷2=3.36
That's the area of one triangle, there's four so:
3.36×4=13.44
Then the square!
3×3=9
13.44+9=22.44 cm^2
I'm not sure if this is the standard way since I didn't learn about pyramids so I used the area stuff, so sorry if its not correct.
Have a nice day!

Y - 3x = -8
y = 3x - 8...slope here is 3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/3.
y = mx + b
slope(m) = -1/3
(3,2)...x = 3 and y = 2
now we sub and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur perpendicular equation is : y = -1/3x + 3
The determinant is found by the formula ad-cb
where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0
12x2 = 24
-6x0 =0
24-0 = 24
the determinant = 24
