The answer is 36. You subtract 6 each time. You multiply 6 by 45 and that equals
Area of triangle: 1/2(base)(height)
Area of rectangle: length × width
Find the area of the triangles on the sides first using 1/2(base)(height).
Plug 8 for the base and 6 for the height.
1/2(8)(6) = 24 units²
Multiply 24 by 2 for both of the triangles.
(24)(2) = 48 units²
Find the area of the rectangles of the object using length × width.
For the rectangle on top, you can find the width using the Pythagorean Theorem: a² + b² = c².
Plug in 6 and 8 for a and b, and find c (width).
6² + 8² = c²
36 + 64 = 100
Square root both sides; √100 = 10.
The width of the rectangle on top is 10.
Now plug 20 for the length and 10 for the width.
20 × 10 = 200 units²
For the rectangle on the bottom, plug in 20 for the length and 8 for the width.
20 × 8 = 160 units²
For the rectangle on the side, plug in 20 for the length and 6 for the width.
20 × 6 = 120 units²
Add up all the areas ⇒ 48 + 200 + 160 + 120 = 528 units².

Step-by-step explanation:
If the figures are congruent, match up letter to letter. Q to P is the same as E to D proportionally.
The domain is the X coordinates.
The bottom black dot is on X =-4 and the top black dot is on X = 6.
Because the dots are solid black, this means the X coordinate is part of the solution ( equal to).
This means the domain is greater than or equal to -4 and less than or equal to 6
which would be written as -4=< x<=6
