Answer:
The height of 5 books of height 7 cm 5 mm each can be calculated as follows:
Height of one book = 7 cm + 5 mm = 7.5 cm
Height of 5 books = 5 x 7.5 cm = 37.5 cm
Therefore, the total height obtained by stacking 5 books of height 7 cm 5 mm each is 37.5 cm.
The perimeter of the square park is 3 m 20 cm, which can be written as 320 cm.
Tania takes 3 complete rounds of the park, so the total distance traveled by her is:
Total distance = 3 x perimeter
Total distance = 3 x 320 cm
Total distance = 960 cm
Therefore, the total distance traveled by Tania is 960 cm or 9.6 m.
