  14. Find the area of a square park whose perimeter is 320 m

ANSWERS:

  1. 10:1
  2. 6 square cm
  3. 0.001
  4. 3.14 or 22/7
  5. -3
  6. 45.87 + 23.54 = 69.41
    69.41 – 12.45 = 56.96
  7. Base = 8 cm, Height = 2 cm
    Area = b x h = 8 x 2 = 16 square cm
  8. CP = 1000 rupees
    SP = 950 rupees
    CP – SP = 1000 – 950 = 50 rupees
    Since CP > SP, there is a loss of 50 rupees
    Loss % = Loss x 100 /CP = (50 x 100) /1000 = 5000/1000 = 5%
  9. 5x – 5 = 5 x 5 – 5 = 25 – 5 = 20
  10. The three sides given are 3 cm, 4 cm and 5 cm
    Now 3 + 4 = 7 > 5
    4 + 5 = 9 >3
    3 + 5 = 8 > 4
    Therefore, sum of two sides is greater than the third side. So such a triangle is possible.
  11. Interest = PRT/100
    = 35000 x 8 x 3 /100
    = 8400 rupees
  12. 0.25 = 0.25 x 100 % = (25/100) x 100% = 25%
    0.02 = 0.02 x 100% = (2/100) x 100% = 2%
  13. 4x + 7y – (2x +4y) = 4x + 7y – 2x – 4y = 2x + 3y
  14. 2(x + 3y) + x – 4y = 2x + 6y + x – 4y = 3x + 2y
    When x = 2, y = 3, 3x + 2y = 3 x 2 + 2 x 3 = 6 + 6 = 12
  15. Perimeter = 320 m
    Length of each side = 320/4 = 80 m
    Area of a square = side x side = 80 x 80 = 6400 square metre.
