दिले:

समभुज चौकोनाचे क्षेत्रफळ = 96 सेमी 2

एक कर्ण = 16 सेमी

वापरलेली सूत्रे:

संकल्पना: समभुज चौकोनाचे कर्ण हे लंबदुभाजक असतात.

समभुज चौकोनाचे क्षेत्रफळ = १/२ x कर्ण १ x कर्ण २

समभुज चौकोनाची बाजू = √[(D 1 /2) 2 + (D 2 /2) 2 ]

⇒ (1/2) x √[(D 1 ) 2 + (D 2 ) 2 ]

गणना:

प्रश्नानुसार

96 = 1/2 x 16 x कर्ण2

⇒ कर्ण2 = 12

आता, समभुज चौकोनाची बाजू = 1/2 x √[16 2 + 12 2 ]

∴ 1/2 x 20 = 10 सेमी
