Question

Jika panjang seluruh kawat 460cm,lebar 25cm,tinggi 10mm,panjangnya adalah?

Answer 1

Keliling balok = 460cm Lebar =25cm Tinggi=10mm=1cm Panjang= ? K= 4*l = 4* 25=100cm = 4*t = 4*1 =4cm = 4*p = 4*p = x 4*p = 460-100-4 4*p = 356 Cm P = 356/4 = 89 cm

Answer 2

460 = 4p+4l+4t 460 = 4p+4(25)+4(1) 460 = 4p+100+4 460 = 4p+104 460-104 = 4p 356 = 4p 356 : 4 = p 89 = p kalo krg meyakinkan dicoba itung aja
