Answer: 69m^2
Step-by-step explanation:
we can find the area of shaded region by subtracting the area of removed region.
so,
area of rectangle= length*width
for area of removed region
=4m*2m=8m^2
for area of larger region
=11m*7m=77m^2
Now final destinaltion
area of shaded region=area of lareger region-area of smaller region
=77m^2-8m^2
=69m^2
The argument is valid by the law of syllogism
•*Ok first let me show you the formula for the Area of the trapezoid.
A=a+b/2 h.(I will be using the letter x for the multiplication sign)
*And here is the formula to find the height of a trapezoid
h=2 x A/a+b (2 times the Area over base "a" plus base "b")
*We need to plug in the numbers: h = 2 x 136.5/6+15
*Next, we add the two bases to get 21: 6+15=21 (h=2 x 136.5)
*Then, divide the total of the two bases (21) from the area to get 6.5: 136.5/21-6.5
*Finally we multiply 2 by 6.5: 2 x 6.5= 13
The height if this trapezoid is 13.
Hope this helps you ☺

B is false, since by the inclusion/exclusion principle,
By independence, we have
