Answer:
B
Step-by-step explanation:
The sum of the angles of the triangle add up to 180 degrees.
x and y are equal to each other in this type of the triangle.
The dimensions of the garden that will require the least amount of fencing are 450 m and 900 m and the perimeter of the area is 1800 m.
<h3>What is the area of the rectangle?</h3>
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Let's suppose x and y are the sides of the rectangular garden and y is the parallel to the river.
Then according to the problem:
2x + y = P ..(1)
P is the perimeter of the rectangle.
xy = 405000 (area of the rectangle)
Plug the value of y in the equation (1) from the above equation.
P(x) = 2x + 405000/x
P'(x) = x—405000/x² = 0
x = 450 m
P''(x) > 0 hence at x = 450 the value of P(x) is minimum.
y = 405000/450
y = 900 m
P(min) = 1800 m
Thus, the dimensions of the garden that will require the least amount of fencing are 450 m and 900 m and the perimeter of the area is 1800 m.

Answer:
the second option is correct, the one that you picked
Step-by-step explanation:
Step-by-step explanation:
principal = 18000
Time = 3 yrs
Rate. = 8%.
CI. = ?
Now
CI = p ( 1+ R÷ 100) ^T
CI = 18000( 1+ 8÷ 100 ) ^ 2
CI = 20995.2
Hope it's is Right :-)
