3. 6. A rectangular classroom is 12 m x 8 m. If the floor of that classroom is to be covered with tiles (ubin) 50 cm x 50 cm, how many tiles are needed?
Jawab:
384 tiles
Penjelasan dengan langkah-langkah:
12 m = 1200 cm
8 m = 800 cm
Class Floor Area :
1200 x 800 = 960000 [tex]cm^2[/tex]
1 tiles area
50 x 50 = 2500 [tex]cm^2[/tex]
Tiles that are needed
960000 [tex]cm^2[/tex] : 2500 [tex]cm^2[/tex]
9600 : 25 = 384 tiles
384 tiles are needed to covered the classroom floor
4. The Length of a rectangular is three time the width of it.The area of the garden is 48m square.find the dimension of the garden
Jawab:
Penjelasan dengan langkah-langkah:
Misalkan Panjang = P dan Lebar = L
P = 3L
Area = 48 m²
Area = P×L = (3L)(L) = 3L²
⇒ 3L² = 48
⇒ L² = 16
⇒ L = 4 m (Tidak mungkin lebar negatif)
Diperoleh P = 3×4 = 12 m
Maka, dimensi kebun: Panjang = 12 m dan Lebar = 4 m

★The area of a square park is the same as of a rectangular park
★ If the side of the square park is 60 m and the length of the rectangular park is 90 m
★ find the breadth of the rectangular park.
[tex]{ \purple{ \large{ \underline{ \pmb{ \frak{ To \: Find : }}}}}}[/tex]
★ The breadth of the rectangular park
[tex]{ \purple{ \large{ \underline{ \pmb{ \frak{ Let's \: understand \: the \: concept : }}}}}}[/tex]
☀️Concept:Now, we have said that the area of square park is equal to the rectangular park. so, we have to find the area of the square park first and then as we know that the area of the rectangular park is the same so, let's find its breadth with the help of he area.
[tex]{ \purple{ \large{ \underline{ \pmb{ \frak{Using \: concept : }}}}}}[/tex]
~ Formula to find the area of a square :
➼ Area of a Square = Side times Side
~ Formula to find the area a rectangle :
➼ Area of a rectangle = Length times Breadth
[tex]{ \purple{ \large{ \underline{ \pmb{ \frak{Full \: solution : }}}}}}[/tex]
~ Now, let's find the Area of the square first Substituting the measurement of its dimension which is 60m using the below mentioned formula
✪ Areaofthesquare=Side×Side
➼ Area of the square = S × S
➼ Area of the square = S²
➼ Area of the square = 60m²
➼ Area of the square = 3600m²
Henceforththeareaofthesquareis3600m²★ We know that,
➼Area of the square = Area of the rectangle
➼ 3600m² = Area of the rectangle
Henceforththeareaoftherectangle= 3600m²~ Now let's find the breadth of the rectangle with the help of its area and the measurement of its length which are 3600m² and 90m respectively Substituting the values in the below mentioned formula.
✪ Areaofarectangle=Length×Breadth
➼ Area of the rectangle = L × B
➼ 3600cm² = 90 × B
➼ B = 3600m²/90m
➼ B = 30m
HenceforththeBreadthoftherectangleis30m[tex]{ \purple{ \large{ \underline{ \pmb{ \frak{Additional \: Information : }}}}}}[/tex]

14. perimeter of rectangular is 40m.The length of rectangular is 15m.The width of rectangular is......cepat yaa
Jawaban:
Perimeter = 2 ( length + width)
40m = 2 length + 2 widht
40m = 2 × 15 + 2 widht
2 widht = 40 - 30
2 widht = 10
widht = 10/2 = 5
perimeter = keliling
length = panjang
widht = lebar
