Consider all rectangles with an area of 200 m squared. Let x be the length of one side of the rectangle.

A) Experss the perimeter of a function of x.

then the width is 200/x

Perimeter(x) = 2(x + 200/x)
= 2x + 400/x

1 x+2=3

To express the perimeter of a rectangle as a function of x, we need to find the formula for the perimeter of a rectangle.

The perimeter of a rectangle is given by the formula:
Perimeter = 2 * (Length + Width)

In this case, the length of the rectangle is x, and the width can be found by dividing the area of the rectangle by the length:
Width = Area / Length

Substituting the values, we can express the perimeter as a function of x:
Perimeter = 2 * (x + (200 / x))

So, the perimeter of a rectangle with an area of 200 m² is expressed as Perimeter = 2 * (x + (200 / x)).

To express the perimeter of a rectangle as a function of x, we first need to know the formula for the perimeter of a rectangle. The perimeter of a rectangle is given by the formula:

Perimeter = 2 * (Length + Width)

In this case, the area of the rectangle is given as 200 m². The area of a rectangle is calculated by multiplying the length (L) and width (W) of the rectangle. So we have:

Area = Length * Width

Since we are given the area as 200 m², we have:

200 = Length * Width

Now, in terms of x, we can consider x as the length of the rectangle. Thus, the width can be expressed as:

Width = Area / Length
= 200 / x

Now, we can substitute this value in the perimeter formula:

Perimeter = 2 * (Length + Width)
= 2 * (x + 200/x)

Therefore, the perimeter of the rectangle can be expressed as a function of x as:

Perimeter(x) = 2 * (x + 200/x)
