Penjelasan dengan langkah-langkah:
1. Diketahui L = 3025m^2
Ditanya panjang sisi dan Keliling
Panjang sisi adalah 55m
Keliling : 4 x sisi
=4×55
=220m
2.
3. L = p×l
= 70cm × 30 cm
= 2.100cm^2
K = 2(p+l)
= 2(70+30)
= 200cm
4. L = p × l
4.000 = 80 × l
l = 4.000/80
l = 50cm
K = 2(p+l
= 2(80+50)
= 260 cm
5. K = 3 × sisi
105 = 3 × sisi
s = 105/3
s = 35 cm
