A rectangular flower bed, 56 meters in circumference, 2 5 times as long as it is wide, what is its l

The sum of length and width is 56 2 = 28 cm, width is 28 (1 + cm, length is 8 cm, area is 8 20 = 160 square cm.

The sum of length and width is: 56 2 = 28 (m).

Width: 28 (1+m).

Length: 8 m) (or 28-8=20).

Area: 20 8 = 160 (sq.m.).

Let the width be x and the length be , then ( width is 8 length is 20 area is 160

Set the width to xThen: 56= solution x=8then the length is equal toWidth=8 Area is equal to 20*8=160

Length + width = 56 2 = 28 (m).

Width: 28 (1+m).

Length = 20 (m).

Area: 20 8 = 160 (sq.m.).

If the width is x, then the length is, 2*x+2*, x=8, length=20, area=length*width=8*20=160

Let the length be a and the width be b;

2（a+b）=56

a=a=20，b=8

ab=160

So the length is 20 meters, the width is 8 meters, and the area is 160 square meters.

Let the length and width be x,y,2(x+y)=56 to obtain x=20 y=8 and area=160

It is 20 meters long and 8 meters wide, with an area of 160 square meters.

If the width is x, the length is.

2（x=8

Set the width to meters.

The width is 8 meters and the length is 20 meters.

Answer: According to the title, the circumference is known to be 56 meters, assuming that the width is x, then the length is 3x, and the equation is obtained

x+3x）×2=56

4x×2=56

8x=56x=7

3x=21 gives a width of 7 meters and a length of 21 meters.

So the area of the rectangular parterr is:

Answer: The rectangular parterre has an area of 147 square meters.

I hope I can dress up the banquet to stop the auspicious state to help you.

= 240 (m).

A: The circumference of this flower bed is 240 meters

Length and width of the friend drain and: 195-2 meters.

Wide: Good wood.

Length: Tangerine rice.

Solution: Let the width of this rectangular flower bed be x meters, then the length is (x + 4) meters, according to the title:

2x+2×（x+4）=86，2x+2x+8=86，4x=78，x=，x+4=

This flower bed is long and wide meters.

If the width is x, the length is x104

2 (xx, xx, x4), x2, 86

x two meters. The length is 4 twelve meters.

The length is meters and the width is meters.

(length + width) * 2 = 86, length + width = 43

Length-width = 4 length = width =

Solution: If the width of the rectangle is x meters, then the length of the rectangle is (x 12) meters. From the meaning of the title.

x＋12＋x）×2＝56

2x＋12＝28

2x＝16x＝8

Long take the traces of the square long:

8 12 20 (m).

The area of the rectangle:

20 8 160 (square meters).

Analysis: The circumference (length and width) of the rectangle 2

The area of the rectangle is led by Choshu wide.

The wide stuffy silver is x m douxiao, and the long ant banquet is x + 12 (m) 2 (x + x + 12) = 56

2x+12=28

x=8 x+12=20

8 20 = 160 (square meters).

Summary. The circumference of a rectangular flower bed is 60 meters, and the width ratio is 8 meters.

Hello! According to the current topic of Zhengyinyuan information, the circumference of a rectangular flower garden is 60 meters, and the width ratio is 8 meters, what is the area of this rectangle? Let's set: the length is x meters, the width is x - 8 meters.

Length, width) 2, 60 (x+x-8) 302 x 38 x 14 meters, length 14 meters.

Width: 14-8 6 meters.

So, the area is 14 6 84

Length(W):2 60(x+x-8) 302x 38x 19 meters, length 19 meters.

Width: 19-8 11 meters.

So, the area is 11 19 209

Final Answer: Area is: 209

Thank you. You're welcome.

Please give me a thumbs up!

Summary. Only these conditions are right, classmates <>

The circumference of a rectangular flower bed is 90 meters, and if the length and width are increased by 5 meters each, the area will increase by how many square meters.

Only these conditions are right, classmates <>

Yes. Only these conditions were given.

In elementary school problems, the method of solving equations is not given.

So the answer is an increase of 550 square meters in area.

Classmate, hail shirt, can you call the source chain cavity ** will not point it out, I will give you a detailed explanation.

Is there a way to use equations?

In the fourth grade of elementary school, I didn't use equations yet.

Pure algebra may be a bit difficult to understand, so I'll write it out first.

You look at this is understandable.
