A rectangular solar panel has length 9 cm and breadth 12 cm. What is the length of the diagonal wiring required?
Show answer & explanation
Correct answer: A
Explanation
Given:
Length = 9 cm
Width = 12 cm
By the formula:
Diagonal = √(l² + b²)
Diagonal = √(9² + 12²)
= √(81 + 144)
= √225
= 15
Diagonal wiring length = 15 cm
