Question

a) A side is 40 cm of a square then calculate it's area and perimeter.

### •Given

• Side of square = 40 cm

### •Tofind

• Area and perimeter of square

### •Solution

Area of square = side × side

⟶ 40 × 40

⟶ 1600 cm²

• Area of square = 1600 cm²

Perimeter of square = 4 × side

⟶ 4 × 40

⟶ 160 cm

• Perimeter of square = 160 cm

Question

b) What is the width of a rectangle, if it's area is 220cm² and length is 22cm.

### •Given

• Area of rectangle = 220 cm²
• Length of the rectangle = 22 cm

### •Tofind

• Width of the rectangle

### •Solution

Area of rectangle = length × breadth

⟶ 220 = 22 × breadth

• Breadth of the rectangle = 10 cm

Correct Question

c)What is the thickness of one notebook if thickness of 12 notebooks is 75 cm.

### •Given

• Thickness of 12 notebooks = 75 cm

### •Tofind

• Thickness of one notebook

### •Solution

Thickness of 12 notebooks = 75 cm

Thickness of 1 notebook = 75/12 cm = 6.25 cm

• Height of 1 notebook = 6.25 cm

Question

d)What will be the breath of carpet if the Length is 36 m and area is 422 m² of hall?

### •Given

• Length = 36 m
• Area = 422 m²

### •Solution

⟶ 422 = 36 × breadth

⟶ 11.72 m

Question

e)Calculate the number of tiles required for tiling the floor, if the size of tile is 3×2cm and area of floor is 660 cm²?

### •Given

• Size of the tiles = 3 × 2 cm
• Area of the floor = 660 cm²

### •Tofind

• No. of tiles required for tiling the floor

### •Solution

Area of the tiles = length × breadth

⟶ 3 × 2

⟶ 6 cm²

No. of tiles required = Area of floor/ Area of floor

⟶ 660/6

⟶ 110 tiles

• No. of tiles required = 110 tiles
