Which statements describe the figure on the grid if each square has side lengths of 1 cm? Check all that apply. On a coordinate

PolarNik [594]

The figure on the grid is an illustration of areas and perimeters of a shape

<h3>How to determine the true statements?</h3>

The question is incomplete, as the figure is not given.

So, I will provide a general explanation on how to determine the area and the perimeter of a shape.

The area of a shape is the amount of space on that shape.

Take for instance a square that has a side length 5 units.

The area of the square would be:

Area = 5 * 5 = 25 square units

On the other hand, the perimeter is the sum of the side lengths of the shape.

Using the same square that has a side length 5 units.

The perimeter of the square would be:

Perimeter = 4 * 5 = 20 units

Joe wants to enlarge the rectangular pumpkin patch located on his farm. The pumpkin patch is currently 40 meters wide and 60 met

vodomira [7]

Answer:

$15x^2+380x+2400$

The diagram is shown below for reference.

Step-by-step explanation:

We are given the length and width of old pumpkin patch as $60$ meters and $40$ meters respectively.

It further says length is increased by $5x$ meters and width increased by $5x$ meters.

So the length of the new pumpkin patch would be $60+5x$ meters.

And the width would be $40+3x$ meters.

We know area of a rectangular shape $=length \times width$

So, plugging the above values, we get the area of the new pumpkin patch as:

$=(60+5x)\times (40+3x)\\=2400+180x+200x+15x^2\\=2400+380x+15x^2\\=15x^2+380x+2400$ on rearranging.

Thus the function of the area of the new pumpkin patch would be:

$f(x) = 15x^2+380x+2400$
