4. Look at the picture. The perimeter of figure A is ... centimeter. Tolong Bantu Saya. Saya tidak mengerti...
Jawaban:
perimeter is keliling. cukup hitung jumlah ukuran garis yang mengelilingi. pada kanan atas terdapat ukuran satu garis adalah 1cm. pada garis atas, ada 3 garis + 5 garis + 2 garis + 4 garis + 3 garis + 4 garis + 2 garis = 23 garis.
sebelah bawah ada10 garis
kanan =3 garis
kiri =8garis
terakhir jumlahkan = 23 + 10 + 3 + 8 = 44 garis
jadi kelilingnya 44 garis atau 44 cm
5. The figure is made up of a square and trapezium. The perimeter of the figure is 60 cm. Find the area of the figure. Use the steps.
Jawab:
The area of the figure is 188 cm².
Penjelasan dengan langkah-langkah:
Form that figure, we know that A and C are both squares. Therefore, the length of the rightmost side of the figure is 8 cm.
Let s be the length of C’s sides.
Given that the perimeter of the figure is 60 cm, we can get:
(14 + 2×8 + 3s) cm = 60 cm
⇔ 14 + 16 + 3s = 60
⇔ 30 + 3s = 60
⇔ 3s = 60 – 30
⇔ 3s = 30
⇔ s = 30/3
⇔ s = 10 cm
Let A be the area of the figure, we can find:
A = the sum of all areas
⇔ A = area of square A + area of trapezium
⇔ A = s² + ½(base+top)×height
⇔ A = 10² + ½(14+8)×8
⇔ A = 100 + 11×8
⇔ A = 100 + 88
⇔ A = 188 cm²
CONCLUSION∴ The area of the figure is 188 cm².

7. figure B is made up of four identical right angled triangles as shown in figure A. Four times the perimeter of figure A is 96cm. The perimeter of Figure B is 48cm. What is the lenght of XY?tolong dibantu sesegera mungkin ya.. thanks. #math#matematika#triangle#perimeter
Jawaban:
6 cm
Penjelasan dengan langkah-langkah:
4(Keliling gambar A) = 96 cm
Keliling gambar A = 24 cm
Gunakan tripel Pythagoras
Segitiga 3-4-5 adalah segitiga siku-siku dan kelilingnya adalah (3+4+5) cm = 12 cm
Kalau mau dapatkan segitiga siku-siku dengan kelilingnya adalah 24 cm, maka tripel Pythagorasnya adalah 6-8-10 (Cuma dikali 2). Karena XY(alas segitiga) lebih pendek daripada tinggi segitiga, maka XY = 6 cm
8. Find the perimeter and area of the composite figure below. BANTU PLISSS
perimeter = π x d + 12 + 12
perimeter = 3,14 x 12 + 12 + 12
perimeter = 37,68 + 24
perimeter = 61,68
Area = 12 x 12 - π x r x r
Area = 144 - 3,14 x 6 x 6
Area = 144 - 113,04
Area = 30,96
9. Look at the picture ! The perimeter of the figure is …bisa bantuin ndak?
Jawaban:
39 cm
Penjelasan dengan langkah-langkah:
maaf kalau salah yah
Jawab:
60 cm
Penjelasan dengan langkah-langkah:
Perimeter : Keliling
Keliling = Jumlah sisi bangun yang ada.
K = 15 + 8 + 25 + 12 = 60 cm.
Terima kasih! Semoga membantu, maaf bila ada yang salah.

17. The figure is made up of an equilateral triangle of side 10 cm and a semicircle. Find the perimeter of the figure. (Take π = 3.14) 10 cm
Jawab:
Penjelasan dengan langkah-langkah:
perimeter of 1/2 circle =1/2x2xphixr=1/2x2x3,14x10=31,4cm now perimeter of isosceles triangle=s1+s2+s3=
10+10+10=30cm=
30cm+31.4cm
= 61.4cm so the combined area of a 1/2 circle with an isosceles triangle is 61.4cm
The perimeter of the figure is 35.7 cm.
The perimeter of the figure is the sum of the perimeter of the semicircle and 2 times the length of the side of the triangle. The diameter of the semicircle equals to the length of the side of the triangle.
(Note that one side of the triangle lies inside the figure, so it is excluded from the sum.)
Solving it:
[tex]\begin{aligned}P&=\frac{1}{2}(\pi d)+2s\\&=\frac{1}{2}(\pi s)+2s\ \ \because d=s\\&=\left(\frac{\pi}{2}+2\right)s\\&=\left(\frac{3.14}{2}+2\right)(10\ \rm cm)\\&=\left(1.57+2\right)(10\ \rm cm)\\&=\left(3.57\right)(10\ \rm cm)\\\therefore\ P&=\boxed{\,\bf35.7\ cm\,}\ \ \sf(answer)\end{aligned}[/tex]
