Given that the area of a square is equal to 5, find the perimeter of the square

Because the side length of the square is root 5, the perimeter of the square is 4 * root 5

A rectangle is a meter in length and B meter in width. (1) first use the formula to express the perimeter and area of the rectangle. (2) when a is 8 and B is 5, what is the circumference

(1) First, use the formula to express the perimeter and area of the rectangle
The circumference of rectangle = (a + b) × 2
Area = ab
(2) When a is 8, B is 5, what is the circumference
Perimeter = (8 + 5) × 2 = 26
Area = 8 × 5 = 40

The perimeter of a rectangle is 32 meters, and the meters of its length and width are two prime numbers. To find the area, we give explanations, ideas and formulas

Length + width = 32 △ 2 = 16 cm
16=13+3=11+5
Therefore, area = 13 × 3 = 39 square meters
Or 11 × 5 = 55 square meters

The perimeter of a rectangular vegetable field is 200 meters, and the ratio of width to length is 3:2?

The length is 20 × 3 = 60 (m), the width is 20 × 2 = 40 (m), and the area is 40 × 60 = 2400 (M2). A: the area of this vegetable field is 2400 square meters

Given that the area of the sector is a square meter and the arc length is a meter, then the radius of the sector is ()
Given that the area of the sector is a square meter and the arc length is a meter, then the radius of the sector is ()

Let the radius be r and the center angle / 360 ° be n
Then the sector area = n π R & sup2; = a
Arc length = 2n π r = a
nπr²=2nπr
So r = 2
So the radius of this sector is (2m)

Known sector area is 50 square meters, do not know arc length, do not know radius, find sector side length

First of all, there is no concept of side length in a sector, only radius, arc length and center angle. Secondly, when the area is determined, at least one quantity must be given, otherwise the shape of the sector cannot be determined. Therefore, there is no solution to this problem

If the length of a diagonal line of the diamond is 12cm and the perimeter is 40cm, the area of the diamond is ()
A. 24cm2B. 48cm2C. 96cm2D. 192cm2

Because the perimeter is 40cm, the side length is 10cm. As shown in the figure: ab = 10cm, AC = 12cm. According to the properties of diamond, AC ⊥ BD, Ao = 6cm, ⊥ Bo = 8cm, BD = 16cm. The area s = 12 × 16 × 12 = 96 (cm2), so C

If the perimeter of the diamond is 40 and the length of one diagonal is 12, then the length of the other diagonal is 12

The four sides of the diamond are equal, all 10
The length of a diagonal is 12 and half is 6
The other side of the right triangle is √ (10 & # 178; - 6 & # 178;) = 8, which is half of the other diagonal of the diamond
Then the length of the other diagonal is (16)

If a diamond has a circumference of 40 cm and a diagonal of 12 cm, what is the height on one side

If the perimeter of the diamond is 40, the four sides are 10
If you cross a little diagonal, the height is 8
The height on one side of it is
12*8/10=9.6

(1 / 2) 1. The circumference of a rectangle is 50 cm, and the ratio of length to width is 3:2. What is the area of the rectangle? 2. A has 50 yuan
(1 / 2) 1. The circumference of a rectangle is 50 cm, and the ratio of length to width is 3:2. What is the area of the rectangle? 2. A has 50 yuan, which is 1 / 5 of the total money of B and C. B's money

1 L + W = 50 △ 2 = 25 cm
Length = 25 ÷ (3 + 2) × 3 = 15 cm
Width = 25-15 = 10 cm
Area = 15 × 10 = 150 square meters
2. B + C = 50 △ 1 / 5 = 250 yuan
B = 2 × (50 + 250) / (2 + 1) = 200 yuan

Given that the area of a square is equal to 5, find the perimeter of the square
