Answer:
AC = 5
Step-by-step explanation:
AC is the diagonal of the rectangle ABCD and splits the rectangle into 2 right triangles.
Using right triangle ABC with hypotenuse AC
Applying Pythagoras' theorem gives
AC² = AB² + BC² ← substitute given values
AC² = 4² + 3² = 16 + 9 = 25
Take the square root of both sides
AC = 
= 5

Answer:
Area = 406
Step-by-step explanation:
First things first: Divide the shape
Here is how I did it:
21 x 16
14 x 5
Now solve:
21 x 16 = 336
14 x 5 = 70
Now add:
336 + 70 = 406
So the area is 406
Make slope form: y = mx + b
8y = 3x + 12
Divide by 8
Y = 3/8x + 12/8
The slope is 3/8
