Nomor 6. Luas suatu persegi = 50 cm² s² = 50 cm² s = √50 s = 5√2 cm Panjang diagonal = s√2 = 5√2 x √2 = 10 cm
Nomor 7 P : L = 4 : 3 3 x P = 4 x L P = 4L / 3 Luas persegi panjang = 48 cm² P x L = 48 (4L/3) x L = 48 4L² = 144 L² = 36 L = 6 cm P = (4x6) / 3 P = 8 cm
Panjang diagonal persegi panjang = √(8²+6²) Panjang diagonal persegi panjang = √100 Panjang diagonal persegi panjang = 10 cm
Luas suatu persegi = 50 cm²
s² = 50 cm²
s = √50
s = 5√2 cm
Panjang diagonal = s√2 = 5√2 x √2 = 10 cm
Nomor 7
P : L = 4 : 3
3 x P = 4 x L
P = 4L / 3
Luas persegi panjang = 48 cm²
P x L = 48
(4L/3) x L = 48
4L² = 144
L² = 36
L = 6 cm
P = (4x6) / 3
P = 8 cm
Panjang diagonal persegi panjang = √(8²+6²)
Panjang diagonal persegi panjang = √100
Panjang diagonal persegi panjang = 10 cm
Semoga dapat membantu.
