If you would like to know the dimensions of the garden, you can calculate this using the following steps:
length ... (2 * x - 4) feet
width ... x feet
area ... 170 ft^2
area = length * width
170 = (2 * x - 4) * x
170 = 2 * x * x - 4 * x
170 = 2 * x^2 - 4 * x
0 = 2 * x^2 - 4 * x - 170 /2
0 = x^2 - 2 * x - 85
1. x = 1 - sqrt(86) = -8.27
2. x = 1 + sqrt(86) = 10.27
length: 2 * x - 4 = 2 * 10.27 - 4 = 16.54 feet
width: x = 10.27 feet
The dimensions of the garden are 16.54 feet and 10.27 feet.
Answer:
l = 10.5 cm and A = 21 cm2
Step-by-step explanation:
Area is w*l
Perimeter is 2(w+l)
Replacing the information known in the problem you can get the length with the perimeter
P = 2(w+l)
25 = 2(2+l)
12.5 = 2 + l
10.5 cm = l
with the length now you can find the area
A = w*l
A = 2*10.5
A = 21 cm2

The area of the sector of the circle will be 759.34 m². It is the amount of area enclosed inside the sector's perimeter.
<h3>What is an area of the sector?</h3>
The area of a circle's sector is the amount of space encompassed inside the sector's perimeter. The origin of a sector is always the circle's center.
The region of a circle encompassed by its two radii and the arc connecting them is known as the sector of a circle.
The given data in the problem is;
is the central angle== 4.485
r is the radius = 18.4 m
The area of a sector of a circle is found as;
Hence the area of the sector of the circle will be 759.34 m².

Step-by-step explanation:
Given
per hour
Required:
Determine the linear function
Let y represent the function and x represent the number of hours
The function can be represented with:
We used minus (-) in the equation because the question indicates that the height of the sculpture reduces.
So, we have:
