செவ்வகத்தின் அகலம் = 8 செ.மீ
செவ்வகத்தின் மூலைவிட்டம் = 17 செ.மீ
பயன்படுத்திய சூத்திரம்:
(மூலைவிட்டம்)2 = (நீளம்)2 + (அகலம்)2
செவ்வகத்தின் பரப்பளவு = நீளம் × அகலம்
கணக்கீடு:
(மூலைவிட்டம்)2 = (நீளம்)2 + (அகலம்)2
⇒ (17)2 = (நீளம்)2 + (8)2
⇒ நீளம் = √(289 - 64)
⇒ நீளம் = √225
⇒ நீளம் = 15 செ.மீ
செவ்வகத்தின் பரப்பளவு = நீளம் × மூச்சு
⇒ 15 × 8
⇒ 120 செமீ2
∴ செவ்வகத்தின் பரப்பளவு 120 செமீ2 ஆகும்.Last updated on Jul 17, 2025
