Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFहम जानते हैं कि समलम्ब का क्षेत्रफल = 1/2 × ऊंचाई × (a + b)
जहाँ, a = आधार के सामानांतर भुजा की लम्बाई
b = आधार
⇒ 18 वर्ग सेमी = 1/2 × 3 × (a + 5)
⇒ 36 = 3a + 15
⇒ 21 = 3a
⇒ a = 21/3 = 7 सेमी
∴ आधार के सामानांतर भुजा की लम्बाई 7 सेमी है|
