Answer 1

Largest straight line that can be put on the floor is the diagonal bt the formula root under L square + b square .
Root under 18 square +24 square =900m = 30 m

Answer 2

Answer:

Concept:

The largest straight line can be drawn on the floor of the hall only through its diagonal.

Step-by-step explanation:

Given:

length = 24 m

Breadth = 18 m

Find:

Length of the Largest line that can be drawn

Solution:

The length of the diagonal of the hall can be found using the Pythagoras theorem.

Length of diagonal

$=\sqrt{24^{2}+18^{2}}\\\\=\sqrt{576+324}\\\\=\sqrt{900}\\\\=30 \mathrm{~m} .$

So, the largest line can be 30 m long.
