Question

the length and breadth of a room are 12 m and 5 m respectively what we would be the largest length of a that can be placed on the floor​

Answer 1

Answer:

60

Step-by-step explanation:

12 x 5  = 60

Answer 2

Here the length and breadth of a rectangular floor are given

Length = 12 m

Breadth = 5 m

We have to find the  largest length can be placed on the floor​

So, the largest length will be the diagonal

Length of diagonal = $\sqrt{length^{2} +breadth^{2} }$

                                = $\sqrt{12^{2} +5^{2} }$

                                = $\sqrt{144+ 25 }$

                                = $\sqrt{169}$

                                = 13 m

Hence, the largest length can be placed on the floor​ will be of 13 m
