Perimeter = 2 = 2 x x 14 = 88 cm

Q10. The side of a square is 15 cm. Find the area of another square whose side is twice the first square.

• 225 sq.cm
• 450 sq.cm
• 900 sq.cm
• None of the above

Solution

Side of another square = 2 × 15 = 30 cm Area of square is side2 = 30² = 900 sq.cm

Q11. A rectangular park is of length 48 cm and breadth 32 cm. It is paved for gardening along its boundary. If the width of the flower bed is 3 cm, find the area to be used for gardening.

• 124 cm²
• 144 cm²
• 444 cm²
• 666 cm²

Solution

In the adjoining figure the shaded portion represents the gardening, Thus, area of the gardening = Area of outer rectangle - area of inner rectangle = (l x b) – {(l - 6) x (b - 6)} = (48 x 32) – (42 x 26) = 1536 –1092 = 444 cm²

Q12. The appoximate value of Pi is

• 3.50
• 3.25
• 3.14
• 3.20

Solution

Pi i.e. has approximate value 3.14 or .

Q13. The length of a side of a square whose area is 441 sq cm is

• 29 cm
• 11 cm
• 31 cm
• 21 cm

Solution

Area of square = 441 sq cm Thus, (side)² = 441 = (21)² Then, side = 21 cm

Q14. Rhombus has a perimeter of 49 cm. Find the length of its side.

• 12.25 cm
• 13 cm
• 11.5 cm
• 15 cm

Solution

Perimeter of rhombus = 4 x (side) 49 = 4 x (side) Thus, side = 12.25 cm

Q15. Rhombus has a perimeter of 28 cm, then what will be the length of its side?

• 7 cm
• 4 cm
• 16 cm
• 14 cm

Solution

Perimeter of rhombus = 28 cm Thus, 4 x (side) = 28 cm Side = = 7 cm

Q16. The area of a triangle is 50 cm². If its base is 25 cm, then the corresponding height is

• 3 cm
• 4 cm
• 5 cm
• 6 cm

Solution

Area of triangle = Thus,

• 48 cm
• 32 cm
• 22 cm
• 36 cm

Solution

Perimeter of a rectangle = 2 x (l + b) = 2 x (12 + 4) = 2 x 16 = 32 cm
