खंभे की लम्बाई = 23 मीटर
पहली खिड़की जमीन से 3√5 मीटर ऊपर है और दूसरी खिड़की जमीन से 4√15 मीटर ऊपर है।
प्रयुक्त सूत्र:
एक समकोण त्रिभुज में,
आधार = √(कर्ण2 - लंब2)
गणना:
यहाँ, गली की चौड़ाई = BC
ΔABO में,
BO = √(AO2 - AB2)
= √(232 - 3√52)
= √(529 - 45)
= √484 = 22 मीटर
ΔOCD में,
CO = √(DO2 - DC2)
= √(232 - 4√152)
= √(529 - 240)
= √289 = 17 मीटर
तब, BC = BO + CO
= 22 + 17
= 39 मीटर
∴ गली की चौड़ाई 39 मीटर है।
