Answer:
24x
Step-by-step explanation:
The total length of all vertical segments is 5x·2 = 10x.
The total length of all horizontal segments is (3x+4x)·2 = 14x.
Then the total length of all perimeter segments is ...
10x +14x = 24x . . . . perimeter of the figure
Answer:
53.33 meters
Step-by-step explanation:
Let AB represents the height of the cliff,
( where, A is top and B is bottom ),
Also, C and D represents the shadow of the cloud and cloud in the sky respectively,
Suppose E is a point in the segment CD,
Such that,
AB = DE = 40 meters,
According to the question,


Since,




Now,



Hence,
The height of the cloud above the lake = CE + ED

150+150+2x=960 (width+width+2 length=perimeter)
subtract 300 from each side
2x=660
divide by 2
x=330
the length is 330 ft
