Pak Subur memiliki sebidang kebun berbentuk persegi panjang dengan luas 2 hektar. Jika lebar kebun adalah 125 meter, tentukan panjang kebun pak Subur tersebut!
- A.
  
  150 meter
- B.
  
  160 meter
- C.
  
  170 meter
- D.
  
  180 meter
Correct Answer
B. 160 meter

Explanation
The area of the rectangular garden is given as 2 hectares, which is equal to 20000 square meters. The width of the garden is given as 125 meters. To find the length, we can divide the area by the width: 20000 / 125 = 160 meters. Therefore, the length of Pak Subur's garden is 160 meters.

Sebuah taman berbentuk persegi. Di sekeliling taman itu ditamani pohon pinus dengan jarak antar pohon 4 meter. Panjang sisi taman itu adalah 65 meter. Berapakah banyak pohon pinus yang dibutuhkan?
- A.
  
  50 pohon
- B.
  
  55 pohon
- C.
  
  60 pohon
- D.
  
  65 pohon
Correct Answer
D. 65 pohon

Explanation
The length of one side of the square garden is given as 65 meters. Since the distance between each pine tree is 4 meters, we can calculate the number of pine trees needed by dividing the length of the side of the garden by the distance between each tree. Therefore, 65 meters divided by 4 meters equals 16.25. However, we cannot have a fraction of a tree, so we round up to the nearest whole number. Hence, 65 pine trees are needed to surround the garden.

Bu Meri memiliki kebun berbentuk jajar genjang. Luas kebun adalah 450 m² dan panjangnya 90 m. Berapa tinggi kebun Bu Meri?
- A.
  
  5 m
- B.
  
  6 m
- C.
  
  7 m
- D.
  
  8 m
Correct Answer
A. 5 m

Explanation
The area of a parallelogram is calculated by multiplying the base length by the height. In this case, the base length is given as 90 m and the area is given as 450 m2. To find the height, we can rearrange the formula: height = area / base length. Plugging in the values, we get height = 450 m2 / 90 m = 5 m. Therefore, the height of Bu Meri's garden is 5 m.

Ali membuat layang-layang yang salah satu diagonalnya 60 cm. Luas layang-layang tersebut 2.400 cm². Tentukan panjang diagonal yang lain!
- A.
  
  60 cm
- B.
  
  70 cm
- C.
  
  80 cm
- D.
  
  90 cm
Correct Answer
C. 80 cm

Explanation
Since the area of a kite can be calculated by multiplying the lengths of its diagonals and dividing by 2, we can use this formula to find the length of the other diagonal. Given that one diagonal is 60 cm and the area is 2,400 cm2, we can set up the equation (60 x d)/2 = 2,400, where d represents the length of the other diagonal. Solving this equation, we find that d = 80 cm. Therefore, the length of the other diagonal is 80 cm.

Suatu belah ketupat memiliki panjang sisi 3a cm. Apabila keliling dari belah ketupat tersebut adalah 36 cm, maka tentukanlah nilai a!
- A.
  
  2 cm
- B.
  
  3 cm
- C.
  
  4 cm
- D.
  
  5 cm
Correct Answer
B. 3 cm

Explanation
The length of each side of the rhombus is given as 3a cm. The perimeter of the rhombus is 36 cm. To find the value of a, we need to divide the perimeter by the number of sides, which is 4. So, 36 cm divided by 4 equals 9 cm. Since each side is 3a cm, we can set up the equation 3a = 9 cm and solve for a. Dividing both sides by 3, we get a = 3 cm. Therefore, the value of a is 3 cm.
