Answer:
Step-by-step explanation:
For two matrix P and Q, the product, say PQ is defined when:
The number of columns of P = The number of rows of Q
Since A is a 2×2 matrix and B is also a 2×2 matrix
Thus both AB and BA are possible.
So AB is:
BA is:

<span> A negative power means the quantity is
in the denominator of a fraction.
(2) to the -1 power means 1/2
6 to the -3 power means 1/(6 to the 3 power).
13xy to the -8 power
means 1 / (13xy to the 8 power)</span>
That's something like 1 / [ (13 to the 8 power) (x to the 8 power) (y to the 8 power) ]

Answer:
Step-by-step explanation:
The perimeter is the sum of the side lengths. Those that are unmarked are assumed to match the length of the nearest parallel side.
Clockwise from upper left, the perimeter is ...
P = 8 + 5 + 4 + 4.5 + 15 + 5.6 + 4 + 5
P = 51.5 . . . feet
__
The area can be figured using the formulas for area of a parallelogram, rectangle, and trapezoid. These are, respectively, ...
- A = bh
- A = bh
- A = (1/2)(b1 +b2)h
parallelogram area = (8 ft)(3 ft) = 24 ft²
rectangle area = (8 ft)(4 f) = 32 ft²
trapezoid area = (1/2)(8 ft +15 ft)(4 ft) = 46 ft²
Then the total area of the figure is ...
A = 24 ft² +32 ft² +46 ft²
A = 102 ft²
_____
<em>Additional comment</em>
The figure shown is impossible. The trapezoid side lengths and height are consistent with a bottom base of length 14, not 15.
