To find the area of the shape which is the shaded area I assume: we must find the sum of the area of the rectangle AECD and triangle BEC
Total Area =area of rectangle AECD + triangle BEC
= 9 * 15 + (1/2) * 6 * 15 = 136 + 45 = 181 square milimeters
Hope that helped!

Answer:
$750
Step-by-step explanation:
The total store area in the building is ...
2500 +625 +625 +2500 = 6250 . . . . square feet.
Then the fraction that can be allocated to store C is ...
(625 ft²)/(6250 ft²) = 0.1
The maintenance fee allocated to store C should be ...
0.1 × $7500 = $750
So we are given the mixed fraction 5 and 1/4 and we are asked to subtract 7/8 each time.
We can make 5 and 1/4 into the improper fraction 21/4.
Now that we have this, we want to create a common denominator to make it easier to subtract. We can easily get the common denominator of 8 by multiplying both sides of the fraction by two.
21 * 2/4 * 2 = 42/8.
Our first term is 42/8, as we start out with it.
Now we can subtract to figure out the rest.
Supposing we don’t include 42/8 as the first term, the next terms would be:
35/8, 28/8, 21/8, 14/8.
Notice how we subtract 7/8 each time. As we have a common denominator, we can ignore the 8 on each fraction and focus on the numerator. We simply subtract 7 from 42 each time.
Hope this helps.
For
|a|=b, solve for
a=b and a=-b
so
|a-4|=3a-6
solve
a-4=3a-6 and a-4=-(3a-6)
first one
a-4=3a-6
minus a from both sides
-4=2a-6
add 6 to both sides
2=2a
divide by 2
1=a
other
a-4=-(3a-6)
a-4=-3a+6
add 3a both sides
4a-4=6
add 4 to both sides
4a=10
divide by 4
a=10/4
a=5/2
a=5/2 and 1
100 x 100............. = 10 000
