The circumference of an isosceles triangle is 80 cm, and the length of its waist is twice that of its bottom. How many cm are the waist and bottom of the isosceles triangle

Bottom edge = 80 (2 + 2 + 1) = 16 cm;
Waist = 16 × 2 = 32 cm
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

It is known that the circumference of an isosceles triangle is 80, the waist length is x, and the bottom edge length is Y1. Write out the function solution of Y with respect to X. 2,
It is known that the circumference of an isosceles triangle is 80, the waist length is x, and the base length is y
1. Write the function solution of Y with respect to X
2. Find the direct function when x = 30
3. When the function is direct y = 8, find the direct of the convenient quantity X
4. Write out the domain process of the function

Solution 1 y = 80-2x (20 < x < 40)
2 when x = 30, y = 80-2 * 30 = 20
3 when the function is straight y = 8, that is 8 = 80-2x
That is, x = 36
3 by
Y＞0
That is 80-2x > 0
That is x < 40
And 2x > y
80=Y+2X＞Y+Y
That is y < 40
That is 2x > 40
That is, x > 20
That is 20 ＜ x ＜ 40

What is the relationship between the area s and perimeter C of a square?
Such as the title

Let the side length of a square be a, then its area is s = a ^ 2 and its perimeter is L = 4A, so the relationship between area and perimeter is s = 1 / 16 times the square of perimeter

Let the perimeter of a square be n and the area be s. write the expression of s expressed by N, in which what is the constant and what is the variable

Square side length a = n / 4,
S=a²=﹙n/4﹚²=n²/16
The variable is n and the constant is 16
