Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेले आहे:
आयताची लांबी = 10 सेमी
आयताची रुंदी = 6 सेमी
आयताची पुनर्रचना समभुज चौकोनात केली जाते.
आयताची परिमिती समभुज चौकोनाच्या परिमितीएवढी आहे.
समभुज चौकोनाचा एक कोन 60° आहे.
वापरलेली संकल्पना:
आयताची परिमिती = 2(L + B)
समभुज चौकोनाची परिमिती = 4(बाजू)
समभुज चौकोनाचे क्षेत्रफळ = (बाजू)2 × sin A
गणना:
आयताची लांबी, L = 10 सेमी
आयताची रुंदी, B = 6 सेमी
आयताची परिमिती = 2(L + B)
⇒ 2(10 + 6)
⇒ 2(16)
⇒ 32 सेमी
आयताची परिमिती = समभुज चौकोनाची परिमिती
⇒ 4(बाजू) = 32
⇒ बाजू = 32/4 = 8
समभुज चौकोनाचे क्षेत्रफळ = (बाजू)2 × sin A [जेथे A समभुज चौकोनाचा कोणताही कोन आहे]
⇒ क्षेत्रफळ = 82 × sin 60°
⇒ 64 × √3/2
⇒ 32√3 cm2
∴ समभुज चौकोनाचे क्षेत्रफळ 32√3 cm2 आहे.
