Answer 1

$\bf{\underline{Question:-}}$

• find length of longest ploe that can be put in a room of dimensions ( 12×9 ×8)m

$\bf{\underline{Given:-}}$

• ▶️ Length = 12m
• ▶️Breadth = 9m
• ▶️Height = 8m

$\bf{\underline{Solution:-}}$

$\bf Longest\: length \:of\: pole = \sqrt{h^2+ r^2 + l^2}$

$\bf→ \sqrt{12^2+ 8^2+ 9^2}$

$\bf→ \sqrt{44 + 64 +81}$

$\bf→ \sqrt{289}$

$\bf → 17$

$\bf{\underline{Hence:-}}$

• The length of longest pole is 17metre
