longest length of pole = daigonal of rectangle = under root ( h² + r² + l²)
under root( 12² + 8² + 9²)
under root (144 + 64 +81)
√289
= 13
under root( 12² + 8² + 9²)
under root (144 + 64 +81)
√289
= 13

Answer:
The right answer is L=17 m
Step-by-step explanation:
Given length l = 12 m
breadth b = 8 m and height h = 9 m
Length of longest pole = √(l² + b² + h²)
=√(12²+8²+9²)
= √(144 + 64 + 81) m
= √289 m
= 17 m
= 17 m therefor the longest pole
