Answer:
The length of rectangular is increasing at a rate 0.5714 meters per hour.
Step-by-step explanation:
We are given the following in the question:
Initial dimensions of rectangular box:
Length,l = 10 m
Width,w = 7 m

We have to find the rate of increase of length.
Area of rectangle =

Differentiating we get,

Putting values, we get,

Thus, the length of rectangular is increasing at a rate 0.5714 meters per hour.
(1) x+y+z=1300
(2) x+y=780 => x = 780 - y
(3) y+z=850 => z = 850 - y
Replace x and z with y in function (1)
780 - y + y + 850 - y = 1300
1630 - y = 1300
y = 330
Therefore, x = 780 - y = 780 - 330 = 450
z = 850 - y = 850 - 330 = 520

Answer:
see below
Step-by-step explanation:
There is no picture attached, but assuming that the circle fits inside the square:
Area of square lawn = 242 ft²
Therefore, length of each side =
=
ft
Therefore, the radius of the circle will be half of this =
= 7.78 ft = 93.34 in
X-axis and y-axis
x=1 and y=25
