Answer» 1)length= 4mbreath= 3.5 mperimeter= 2(length+breath) = 2(4+3.5) =2×7.5 =15m2 figer)length= 21m , breath= 7mperimeter= 2(length+breath) = 2(21+7) = 2×28 = 56 m3rd figer)length=15m, breath= 0.2mperimeter= 2(length+breath) =2(15+0.2) = 2(15.2) = 30.4 m 1) 15m2)56 m3) 30.4m are the perimeters of the given figures and the best answer. the answers are 15m 56m30.4mrespectively a) perimeter=4+3.5+4+3.5 =15 cmb) perimeter=21+7+21+7 =56m C) perimeter=15+20+15+20 =70 cm 1) l=4cm , b=3.5cmP= 2(l+b) = 2(4+3.5) =2(7.5) = 15 cm 30.4 cm. cm is the correct answer me 15cm,56cm,30.4 cm is the correct answer of the given question 15,56,30.4 is the correct answer perimeter is total of length soa) = 4+3.5+4+3.5 =15cmb) = 21+21+7+7 = 56cmc) = 15+15+ (20 +20 ) = 70cm |
