$\huge \red {\underline {Given :- }}$

Length = 8 m 50 cm = 850 cm  

Breadth = 6 m 75 cm = 675 cm  

Height = 4 m 50 cm = 450 cm

HCF of given dimensions

$\huge \blue {\boxed {\boxed {\mathbb {solution:- }}}}$

we have to find the HCF of 825, 675 and 450 .

825 = 5 × 5 × 3 × 11

675 = 5 × 5 × 3 × 3 × 3

450 = 2 × 3 × 3 × 5 × 5

HCF = 5 × 5 × 3

HCF = 75 cm.

Hence, the length of the longest rod which can measure the three dimensions of the room exactly is 75 cm.

Answer 2

Answer:75 cm

Explanation:Given,

Length: 825 cm

Breadth: 675 cm

Height: 450 cm

We need to find the longest tape. Since measuring tape would be smaller than 825, 675 and 450, we find HCF.

Therefore,

825 = 3 x 5 x 5 x 11

675 = 3 x 3 x 3 x 5 x 5

450 = 2 x 3 x 3 x 5 x 5

So HCF = 3 x 5 x 5

Longest measuring tape = 75 cm.

Hope it helps!
