Let the height of the trees are h1,h2 and h3,
Then,we know that
Mean height=(h1+h2+h3)/3
15 is divisible by 5 because the last digit of 15 is 5.
A number is divisible by 5 if the last digit of the number ends in 0 or 5
How to solve shaded regions on a trapezoid is simple.
First find the area of the whole trapezoid, or W but it already gives us that as 21.66 in squared.
Next, find the area of the non shaded region, or NS.
3.8*4.6=17.48 in
Lastly, subtract the NS from the W.
21.66 -17.48 =
NS= 17.48 in squared.
W= 21.66 in squared.
S= 4.18 in squared.
The answer is B- 4.18 in Squared
