Test: Mapping Your Way - 2 - Class 5 MCQ

Given: The height of the building is 10m.

10m is represented by 10cm on the map.

We know that 1m = 100cm

Therefore, 10 cm: 10 m ⇒ 10 cm: 1000 cm

Scale used ⇒ 1:100

It means that 1 cm on the map = 100 cm in real life

The outer sides are:

• 7 cm
• 7 cm
• 5 cm
• 5 cm

Now, add these sides together:
7+7+5+5 = 24 cm
Perimeter of the figure: The perimeter of the figure is 24 cm.

- The perimeter of a square is the total distance around it, calculated as 4 times one side of the square
- Given perimeter: 60 cm. So, 4 times side = 60
- One side = 60/4 = 15 cm
- Area of a square = side x side
= 15 x 15 = 225 cm²
- Correct answer: B. 225 cm².

On calculating the number of shaded boxes, we can find that there are 21 shaded boxes.

Since area of 1 box = 1  m², the area of 21 boxes = 21  m²

The perimeter of the square is equal to the perimeter of the rectangle.

• The rectangle has a length of 24 cm and a breadth of 20 cm.
• Calculate the perimeter of the rectangle:
  • Perimeter = 2 × (24 cm + 20 cm) = 88 cm
• Since the perimeter of the square is the same, it is also 88 cm.
• Formula for the perimeter of a square: 4 × side length = 88 cm
• Solve for the side length:
  • Side length = 88 cm ÷ 4 = 22 cm
• Calculate the area of the square:
  • Area = side length × side length = 22 cm × 22 cm = 484 cm²

Therefore, the area of the square is 484 cm².

As can be seen from the map, all the states except Uttar Pradesh in the given options have sea on at least one side.

Therefore, Option C is the correct answer.

• Area of rectangle ABCD = 8×6=48 cm²
• Area of triangle DCE = 1/2×5×6=15 cm²
• Total area = 48+15=63 cm²

The display board is exactly opposite to the blackboard.

Therefore, Option D is the correct answer.

- The purpose of using a scale in a map is to determine the distance between two places.
- A map scale indicates the relationship between a unit of length on the map and the corresponding distance on the ground.
- It helps in converting map measurements to real-world distances.
- Scales can be represented as a ratio (e.g., 1:100,000) or a graphic bar.
- By using a scale, map readers can accurately gauge the distance and size of areas on a map.

- A compass needle always aligns itself with the Earth's magnetic field.
- It points towards the magnetic north pole, not the geographic north pole.
- This is due to the needle being a magnet, with its north pole attracted to the Earth's magnetic north.
- The correct answer is A: North.
- Remember, magnetic north can slightly differ from true north due to variations in the Earth's magnetic field.
