Answer:
75cm tape
Step-by-step explanation:
Length of the room = 825 cm
Breadth of the room = 675 cm
Height of the room = 450 cm
Let us factorize all three given dimensions.
825 = 3 × 5 × 5 × 11
675 = 3 × 3 × 3 × 5 × 5
450 = 2 × 3 × 3 × 5 × 5
Hence, 3, 5 and 5 are the common prime factors here.
So, H.C.F =3 × 5 × 5
H.C.F = 75 cm
Therefore, we need 75 cm the longest tape to measure the three dimensions of the room.
