A rectangle, the ratio of length to width is 3:2, the length is 10 meters It's length, not circumference

A rectangle, the ratio of length to width is 3:2, the length is 10 meters It's length, not circumference

Width: 2 / 10 × 3 / 20
Area: 10 × 20 / 3 = 200 / 3
(/ equal to fraction line)

If the area of a rectangle is 64 square meters, its width is 4 meters, and its length is 16 meters

A: the length of a rectangle is 16 meters

The area of a rectangle is 5 square meters. After increasing its length and width by 10%, how many square meters is the area of the rectangle

The original rectangle is a in length and B in width
ab=5
Increase its length and width by 10%
The length is 1.1a and the width is 1.1b
Area = 1.1a * 1.1b = 1.21ab = 6.05

It is known that the area of a rectangle is 64 square meters and its perimeter is 40 meters?

Let the length be x meters and the width be y meters
According to the meaning of the title
Area = x * y = 64
Perimeter = 2 (x + y) = 40
The solution is x = 16, y = 4
So it is 16 meters long and 4 meters wide

The area of a rectangle is 600 square meters. The length and width of a rectangle must be an integral number of ten. How many situations will happen to its length and width?

10m wide and 60m long
20m wide and 30m long
15m wide and 40m long
12m wide and 50m long

Let the area of the rectangle be s, and the length and width be a and B respectively. If s = √ 42cm & # 178;, B = √ 6cm, find a

7 under root

If s is the area of a rectangle, and a and B are the length and width, respectively, then the formula for the area of a rectangle is s=

ab

Let the length B of the rectangle be constant and the area s of the rectangle be equal to the width a?

We can set the width as 1cm, then the length is 30cm. If the length of a rectangle remains the same, the width is doubled, and the area is 60cm2; if the length is doubled, and the width is doubled, then the area is 30cm2

The area of a rectangle is 864 square meters. Its width is 12 meters less than its length. How many meters is the length and width of a rectangle?
Big brother, big sister, that's the formula
++Formula

Let the width of the rectangle be X,
(12+x)*x=864
The solution of the equation is x = 24
It is 24 in width and 36 in length

The area of a rectangle is 864 square meters. Its length is 12 meters more than its width. How many meters is the sum of its length and width?

The width is x m and the length is x + 12 M;
Area of rectangle = length × width
x（x+12）=864
x²+12x=864
x²+12x-864=0
（x+36）（x-24）=0
X1 = - 36 (negative value rounded off)
X2 = 24 (m) (width of rectangle)
Length is x + 12 = 24 + 12 = 36 (m)
So: the sum of length and width of rectangle = 24 + 36 = 60 (m)
