4. the area of a square is 49cm what is the perimeter of the square
[tex] {s}^{2} = 49 \\ s = \sqrt{49} \\ s = 7 \: cm\\ \\ perimeter \: = 4s = 4(7) = 28 \: cm[/tex]
5. A (-2,1) and B (6,5) are the opposite ends of the diameter of a circle. Find the coordinates of its centre.
we can find the coordinate of the circle centre by using the mean formula for the x and y
point A (-2,1)
x1 = -2 and y1= 1
point B (6,5)
x2 = 6 and y2 = 5
circle centre coordinate
[tex]x = \frac{x1 + x2}{2} = \frac{ - 2 + 6}{2} = \frac{4}{2} = 2[/tex]
[tex]y = \frac{y1 + y2}{2} = \frac{1 + 5}{2} = \frac{6}{2} = 3[/tex]
so, the centre of the circle is (2,3)

8. Math 1. The area of a square is 49 square centimetres. Find the perimeter of the square. 2. The length of a rectangle is 13 cm. What is the width if the area is 65 square centimetres? 3. The are of rectangle is 48 square centimeters, If its length is 8 cm, what is its perimeter?
Jawaban:
1. luas = sisi x sisi
49 = sisi ²
sisi = 7cm
perimeter = 7x4 = 28
2. luas = panjang x lebar
65 = 13 x lebar
lebar = 5cm
width = 5cm
3. luas = panjang x lebar
48 = 8 × lebar
lebar = 6
perimeter = 6x2 + 8x2
= 28

10. The area of a square is 64 cm². What is the length of the squaretolong jawab ya
Answer =
L = 64
L = s²
⇒ 64 = s²
⇒ s = √64
⇒ s = 8
so the side length of the box is 8 cm
Sorry if wrong

12. 8. What are the coordinates of the turning point of the parabola y = x² - 4x + 3? * A. (-2,-1) B. (-2,1) C. (2,-1) D. (2,1)
Jawaban:
C. (2 -1)
Penjelasan dengan langkah-langkah:
Cari x
x= -b/2a
x= -(-4)/2(1)
x= 4/2
x= 2
Masukkan:
y= 2²-4(2)+3
y= 4-8+3
y= -4+3
y= -1
(2, -1)
13. · The coordinates of the parallelogram ABCD are: A = (5,2), B = (2, 4), C = (6, 7) and D= (9,5). What is the length of the shorter diagonal of parallelogram ABCD?
Jawab:
[tex]\sqrt{26}[/tex]
Penjelasan dengan langkah-langkah:
Rumus jarak titik P(a, b) dengan titik Q(c, d) adalah [tex]|PQ|=\sqrt{(c-a)^2+(d-b)^2[/tex]
diagonal dari jajar genjang tersebut adalah AC dan BD. dengan rumus jarak dua titik didapat
[tex]|AC|=\sqrt{(6-5)^2+(7-2)^2}=\sqrt{1+25}=\sqrt{26}\\|BD|=\sqrt{(9-2)^2+(5-4)^2}=\sqrt{49+1}=\sqrt{50}\\\\[/tex]
karena yang diminta panjang diagonal terpendek, maka panjangnya adalah [tex]\sqrt{26}[/tex]
14. the figure below is made up of a rectangle and a square. the ratio of the area of the square to area of the rectangle is 2:5. if 0.25 of the square is shaded, what fraction of the figure is unshaded?
gambar dibawah ini dibuat dari sebuah persegi panjang dan sebuah persegi. perbandingan daerah persegi dibandingkan dengan persegi panjang adalah 2:5 jika 0,25 dari persegi tersebut diarsir. berapa bagian dari gambar yang tidak diarsir?
15. The sum of two square numbers is 25².what are the square numbers?
Jawab:
Simplify 25^2 to a real number
25x25= 625
Then, find out which 2 square numbers add to become 625.
625= 20^2+15^2
625= 400+225
So, the square numbers are 20^2 and 15^2
Penjelasan dengan langkah-langkah:
Jawab:
15² and 20²Penjelasan dengan langkah-langkah:
Square number = product of the multiplication of 2 same numbers
The product of 25² =
25 × 25 =
625
The sum of two square numbers = 625
225 + 400 = 625
15² + 20² = 25²

16. The perimeter of a square is 36 m. What is the length of the side of the square
Answer:
Lengthofsquare:
Perimeter = length²
36 = length²
l = √36
l = √6²
l = 6cm
the length of square is 6cm
[tex]{\color{aqua}{\boxed{\mathfrak{LordKeyarga23}}\:}}[/tex]
Jawab:
a = 9 m

18. the area of square is 2√2+3. what is the length of a side of the square
Penjelasan dengan langkah-langkah:
Known : area of square = 2✓2 + 3 = 2√5 or 5.9
Asked? ; length of the square..
formula :
lengt of side = √area of square
[tex]length of \: side \: = \sqrt{area} \\ = \sqrt{5.9} \\ = 2.5[/tex]
Thankyou..
