Question. Area of a rectangle = length × _____.
Answer: width (or breadth)
Explanation: The area is the flat space inside, which you find by multiplying how long the rectangle is by how wide it is.

Question. Area of a square of side 1 cm equals _____ sq cm.
Answer: 1
Explanation: For a square, multiply side by side: 1 cm × 1 cm = 1 square centimetre.

Question. The perimeter of the square having side 7 cm is _____ cm.
Answer: 28
Explanation: A square has 4 equal sides. Walking all the way around takes 4 × 7 = 28 cm.

Question. Area of a square = side × _____.
Answer: edge (or side)
Explanation: Since all sides of a square are identical, you multiply side by side to see how many square units fit inside.

Question. The perimeter of the rectangle with dimensions 8 cm and 5 cm is _____ cm.
Answer: 26
Explanation: A rectangle has two lengths and two breadths: 8 + 8 + 5 + 5 = 26 cm (or 2 × (8 + 5) = 26 cm).

Question. Area of a rectangle of dimensions 1 m and 2 m is _____ square metres.
Answer: 2
Explanation: Multiply the two sides: 1 m × 2 m = 2 square metres.

Question. A grid design made of 7 rows and 7 columns of 1 sq cm squares has an area of _____ sq cm.
Answer: 49
Explanation: 7 rows with 7 small squares in each row gives 7 × 7 = 49 square centimetres in total.

True or False

Question. Perimeter is the total boundary distance around a closed shape.
Answer: True
Explanation: Perimeter is like putting a fence around a garden—it measures the total path all the way along the outside edge.

Question. A square with side 4 cm has an equal perimeter and area quantity of 16.
Answer: True
Explanation: Perimeter = 4 × 4 = 16 cm, and Area = 4 × 4 = 16 sq cm. Their numbers are both 16!

Question. The area of a rectangle with length 5 cm and width 2 cm is 10 sq cm.
Answer: True
Explanation: Area = length × breadth = 5 cm × 2 cm = 10 sq cm.

Question. If each small tile on a grid is 1 sq cm, a shape made of 16 tiles has an area of 20 sq cm.
Answer: False
Explanation: If there are 16 tiles of 1 sq cm each, the area must be exactly 16 sq cm, not 20.

Question. To calculate the perimeter of a rectangle, we multiply length by breadth.
Answer: False
Explanation: Multiplying length by breadth gives the area! To find perimeter, you add all 4 outer sides: 2 × (length + breadth).

Question. A square possessing side 20 cm has an area of 400 sq cm.
Answer: True
Explanation: Area of a square = side × side = 20 × 20 = 400 sq cm.

Questions / Short Question Answers

Question. Calculate the perimeter of a triangle whose sides are 8 cm, 9 cm, and 12 cm.
Answer: 29 cm
Explanation: Add up all three boundary sides: 8 + 9 + 12 = 29 cm.

Question. Find the boundary of a square whose side is 14 cm.
Answer: 56 cm
Explanation: A square has 4 equal sides, so multiply the side length by 4: 4 × 14 = 56 cm.

Question. What is the area of a rectangle measuring 15 cm in length and 10 cm in breadth?
Answer: 150 cm² (or 150 sq cm)

Question. If a square has a perimeter of 4 cm, what is the true area of the square?
Answer: 1 cm²
Explanation: If 4 equal sides add up to 4 cm, each side is 4 ÷ 4 = 1 cm. Then the area is 1 cm × 1 cm = 1 cm².

Match the Following

Question. Match each geometric figure in Column A with its calculated perimeter or area in Column B:

Explanation: Perimeter is the sum of outer borders (4 × side for a square, 2 × (l + b) for a rectangle). Area is the flat space inside (side × side for a square, length × breadth for a rectangle).
