Answer:

390 m (perpendicular to river) x 780 m (parallel to river)

Step-by-step explanation:

Let y be the length of the side parallel to the river, and let x be the length of the sides perpendicular to the river.

The total area and length of fence required are given by:

Rewriting the length of fence as a function of only x:

The value of x for which the derivate of L(x) is zero is the length of x that uses the least amount of fencing:

If x = 390 m, then:

The dimensions that will use the least amount of fencing are 390 m x 780 m

Which drawing shows two lines that intersect at Point a ax, tab, two lines ab, straight x a.​
leonid [27]

The drawing which shows two lines that intersect at Point, A is as represented in Choice 1: Top-left corner.

Discussion:

In geometry, a line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth.

  • Lines are therefore an idealization of such objects, which are often described in terms of two points or referred to using a single letter.

Ultimately, The drawing which shows two lines that intersect at Point, A are as represented in Choice 1: Top-left corner.

What is the area of this rectangle in square yards?
Vikentia [17]
In the comment of the other answer, you said that the rectangle is 24 x 18 ft.

First, we have to find out how many square feet that is, and then we can convert it to square yards.

The area of a rectangle is the length multiplied by the width.

A = l x w
A = 24 x 18
A = 432 square feet

To find out how many square yards that is, we divide it by 3, because 1 yard is 3 feet.

432 ÷ 3 = 144

The area of a 24x18ft rectangle is 144 square yards.
