Find the length and perimeter of a rectangle if its width is 19 m and its area is 475 m?.

Allisa [31]

The length of the rectangle is: 25 m

The perimeter of the rectangle is: 88 m

<h3>What is the Area and Perimeter of a Rectangle?</h3>

Area of a rectangle = (length)(width).

Perimeter of a rectangle = 2(length + width).

Give the following:

Width of rectangle = 19 m

Area of rectangle = 475 m²

Find the Length using the area formula:

475 = (length)(19)

475/19 = length

Length of the rectangle = 25 m

Find the perimeter of the rectangle

Perimeter of the rectangle = 2(25 + 19)

Perimeter of the rectangle = 2(44)

Perimeter of the rectangle = 88 m

Thus, the length of the rectangle is: 25 m

The perimeter of the rectangle is: 88 m

the length of a rectangle is 4 inches greater than the width. the perimeter of the rectangle is 24in what are the dimensions of

Murljashka [212]

Let's say:
lengh=x
width=y

"The length of a rectangle is 4 inches greater than the width."
That means: x=y+4 (in inches).

the parameter is (by definition) 2*lenght+2*width.

so we have 2*x+2y=24.
we also know that x=y+4

Substituting:

2*(y+4)+2y=24.
2*y+8+2y=24
4*y+8=24//substitute 8 from both sides
4*y=16//dividing both sides by 4.

y=4
So the width is 4!

The lenght is y+4=8!
the dimensions are 4 by 8.
(check: 2*4+2*8=24, correct!)

Eddi Din [679]

If we were to put this in terms of a venn diagram, we would have 360 owning only brand X, 500 owning only brand Y, and 80 in between, owning both. Therefore, 80 out of the 580 owners of brand Y may have X as well, which we put into fraction form 80/580, and reduce to 4/29.
