The circumference of a rectangular piece of land is 200 meters, and the length is 5 times the width

The length is x and the width is y

2x+2y=200

x=5y to solve the equation.

Get. 12y=200

y=50/3

x=250/3

Area = 12500 9

Solution: Let the width of this land be x meters, and the length of this land be 5 x meters.

Then: 2(x+5x)=200

12x=200

x=50/3

At this time: (50 3) * 5 (50 3) = 12500 9 (square meters) Answer: The area of this land is 1250 9 square meters.

Let the width be x meters Then the length is 5 x meters From the inscription: (x 5x) 2 200 solution x 50 3 5x 250 3 Area 50 3 250 3 12500 9 square meters.

Solution: If the width is x, the length is 5x.

5x+x=200÷2

6x=100

x≈1717×5=85m

85 17 1445 (sq.m.).

Let the width be x and the length is 5x, that is: 2(x+5x)=200 to find x!

The formula for the area is: length times width!

I'm sure you can ask for it now!!

It also counts out that it is also 12500 9

Why isn't it an integer?

Everyone is right, how do you choose?

The area of this land is 1,600 square meters.

Width = 200 2 (1+4) = 20m

Length = 4 * 10 = 80m

Area = 20 * 80 = 1600 square meters.

If the circumference is 70, then length + width = 35, Hunger and longevity are twice as wide as the rotten feast, width = 35 3, length = 70 3

s=35／3×70／3=2450／3

A: The area of the plot is 450 square meters.

Solution: Width and length.

Circumference (length and width) 2

Circumference (length) 2

Long 23 long mill Zen.

Length: Circumference 3 90 3 30 meters.

Width and length meters.

Blind cherry blossom dust length and width 30 15 450 square meters.

The width is a multiple of the long calendar, the width of the brother is 1 2, the width is x, the length is 2x, the limb dust is x+2 x 2, equal to 6x, six x = 90 meters, x = 15, then, the width of this rectangle is 15, the length is 30, and the area of the rectangle is the length times the width is equal to 15 30, which is equal to 450, square meters.

Let the length be 2x and the width be x 2x+x=360 2

Then x=60 area=60*120=7200 square meters.

240 2 = 120 (meter imitation hand talk).

70 (m for bumps).

120-70 = 50 (meters).

70 50 = 3500 (square meters).

Answer: The area of this rectangular plot is 3,500 square meters

120/（1+4）=24

A rectangular piece of land, four times as long as it is wide. The circumference is 120 meters. The area of this rectangle is 2,304 square meters.

A rectangular piece of land, the circumference is 50 meters, the length is a time of the width, to find the area of this land, first ask for length and width. Length = Width, Circumference = (Length + Width) 2

Then, circumference = (width + width) 2 = 50

It can be solved wide by 11 and long

Area = length and width.

1 mu = 666 square meters, about 800 square meters per acre, 50 meters long, 16 meters wide.

Solution: Let the width be x meters, which length is, the column is expressed, according to the formula for the perimeter of the rectangle: (

x = 2 meters, length = meters, according to the formula for the area of the rectangle: square meters.

A: The area is square meters.

How many square meters is the area of a rectangular piece of land, with a circumference of 50 meters and a length of several times its width?

2 (length + width) = 50

Length = Width. Length + width = 25

Width + width = 25

Width = 25 width = meters.

Length = meters.

The area of the land is 1,600 square meters.

Width = 200 2 (1+4) = 20m

Length = 4 * 10 = 80m

Area = 20 * 80 = 1600 square meters.
