Question

Amul, is an Indian dairy cooperative society, based at Anand in the

Gujarat. Formed in1946, it is a cooperative brand managed by a

cooperative body, the Gujarat Co-operative Milk Marketing

Federation Ltd. (GCMMF), which today is jointly owned by 36 lakh

(3.6million) milk producers in Gujarat. Amul spurred India’s White

Revolution, which made the country the world’s largest producer

of milk and milk products.



Survey manager of Amul dairy has recorded monthly expenditures

on milk in 100 families of a housing society. This is given in the

Answer 1

Answer:

उत्तर :

त्रिकोणाची परिमिती 40.97 सेमी आहे.

Step-by-step explanation:

दिलेले आहे :

• चौरसाची बाजू = 12 सेमी

शोधा :

• चौरसाचा कर्ण कापला तर तयार झालेल्या त्रिकोणा पैकी एका त्रिकोणाची परिमिती

स्पष्टीकरण :

चौरसाची बाजू = 12 सेमी

(विस्तृत स्पष्टीकरणासाठी दिलेली आकृती पहा)

∆ ABC

(कर्ण)² = (पाया)² + (उंची)²

⇒ (BC)² = (AB)² + (AC)²

⇒ (BC)² = (12)² + (12)²

⇒ (BC)² = 144 + 144

⇒ (BC)² = 288

⇒ BC = \sqrt{288}

288

⇒ BC = 16.97

कर्ण = 16.97 सेमी

★ त्रिकोणाची परिमिती :

∆ ABC

⇒ BC = 16.97 सेमी

⇒ AB = 12 सेमी

⇒ AC = 12 सेमी

त्रिकोणाची परिमिती = तिन्ही बाजूंच्या लांबीची बेरीज

⇒ BC + AB + AC

⇒ 16.97 + 12 + 12

⇒ 40.97

त्रिकोणाची परिमिती = 40.97 सेमी

∴ त्रिकोणाची परिमिती 40.97 सेमी आहे.
