Easy Level Worksheet

Very Short Answer Questions (1 Mark Each)

(1) Write the formula for the perimeter of a square.

Correct! The perimeter of a square = 4 × side = 4a.

(2) Find the perimeter of a rectangle whose length = 8 cm and breadth = 5 cm.

Perfect! Perimeter = 2(l + b) = 2(8 + 5) = 26 cm.

(3) If the side of a square is 6 cm, find its perimeter.

Excellent! Perimeter = 4 × 6 = 24 cm.

(4) Write the formula for the area of a rectangle.

Great! Area of rectangle = length × breadth.

(5) Find the area of a rectangle whose length = 10 cm and breadth = 4 cm.

Correct! Area = 10 × 4 = 40 cm2.

Short Answer Questions (2 Marks Each)

Answer each question clearly

(1) A square park has each side of 12 m. Find its perimeter.

Excellent! Perimeter = 4 × 12 = 48 m.

(2) A rectangle has length 15 cm and breadth 7 cm. Find its area.

Perfect! Area = 15 × 7 = 105 cm2.

(3) Find the side of a square whose perimeter is 36 cm.

Correct! Side = Perimeter ÷ 4 = 36 ÷ 4 = 9 cm.

(4) A rectangular garden has length 25 m and breadth 10 m. Find its perimeter.

Great! Perimeter = 2(25 + 10) = 2(35) = 70 m.

(5) Find the area of a square of side 14 cm.

Perfect! Area = 14 × 14 = 196 cm2.

Long Answer Questions (4 Marks Each)

Note: Answer each question with complete steps and clear explanations.

(1) A rectangular playground is 50 m long and 30 m wide. Find its: (a) Perimeter (b) Area.

Perimeter: m Area: m2

(2) A square tile has side 20 cm. Find how many such tiles are required to cover a floor of area 4 m2.
