(Topic-HCF)​

Answer 1

Answer:

longest tape is

Step-by-step explanation:

L = 8.25 m = 825 cm

75cm825 = 3 * 5 * 5 * 11

B = 6.75 m = 675 cm

675 = 3 * 3 * 3 * 5 * 5

H = 4.50 m = 450 cm

450 = 2 * 3 * 3 * 5 * 5

HCF (825, 675, 450) = (3 * 5 * 5) = 75.

So, longest tape of 75 cm length can be used.
