Answer:
Length 
inches
Width 
inches
Step-by-step explanation:
Let 
= length of rectangle, 
= width of rectangle
Given the area and the perimeter of the rectangle, we can write:
So:
Now, we can use substitution to find the value of :
(Quadratic equation)
∴ 
We can use substitution again to find the value of
∵ Length usually refers to the longer side of a rectangle, ∴ length inches and width 
inches.
Hope this helps :)
Probably is 64% I just think it’s is but I’m not sure
N>4 bc it is not too bad and
Let the distance of Jill form the base of the tower be x, then tan 40 = 100/x
x = 100/tan 40 = 100/0.8391 = 119.18 meters
Let the height of the tower from the level of the top of Jill's apartment be y, then tan 30 = y/119.18
y = 119.18 x tan 30 = 68.8 meters
Therefore, the height of Jill's apartment is 100 - 68.8 = 31.2 meters
