Bear with my working out lol,

8x3 = 24in^2
9x12 = 108in^2
6x7 = 42in^2
(11x4) / 2 = 22in^2

Total = 196in^2

Try that, I couldn’t tell where the tip on the triangle fell at. So it could be wrong but that is what I got and what I would put :)

Answer:

198 in²

Step-by-step explanation:

The dashed lines in the attached figure show how this can be divided into rectangles and a triangle. The area of each rectangle is the product of its length and width. The area of the triangle is half the product of its base and height.

Working left-to-right, the areas of the four partitions total ...

(7×6) +(9×9) +(3×17) +1/2(4×(5+7))

= 42 +81 +51 +24

= 198 . . . . square inches

Anestetic [448]

There are four quantum numbers: n, l, ml and ms. When the orbital is 4d, the 4 is corresponding to n. Thus, n=4. Then, the d corresponds to l = 2. Now, to find the value for ml, take the values of -l to +l. Therefore,

ml = -2, -1, 0, 1, 2

Then,ms could only be either +1 or -1.
