Answer 1

Answer:

4cm length of the rod can measure the dimensions of the room exactly.

Step-by-step explanation:

7 m 20 cm = 720 cm

6 m 40 cm = 640 cm

5 m 96 cm = 596 cm

The length of the rod which can measure the dimensions of the room exactly = HCF of Length , Breadth and Height

720 = 2 × 2 × 2 × 2 × 3 × 3 × 5

640 = 2 × 2 × 2 × 2 × 2 × 2 × 5

596 = 2 × 2 × 149

HCF = 2 × 2 = 4

Answer 2

Answer:

HCF = 400 cm

Step-by-step explanation:

hcf is 4m = 400cm
