Answer:
length =
21 inches
Step-by-step explanation:
Missing information
In this question some information is missing the width is not given in the question .The width in this question is 4 inches we have to find the length of the rectangle .
We know that the perimeter of rectangle is given as
........................equation(1)
where p=perimeter
w= width
l= length
Now putting the value of width and perimeter in the equation(1) we get ,
50=8+2l
50-8=2l
42=2l
Therefore length of the dimension is 21 inches
Answer:
The building is 76 feet tall
Step-by-step explanation:
Since the tree is halfway beween the stake and the building, then if D is the distance between the building (at ground level) and the stake, then the tree forms with the stake a rectangle triangle with base length equal to D/2 and Height equal to 38 feets.
The stake and the top of the buidling also form a triangle rectangle with base length equal to D. Since rectangle triangle preserve proportions, if we double the length of the base without changing the angle, then the heigth should also be doubled, and as a consecuence, the height of the building is 38*2 = 76 feets.
