Matematika SMP Kelas VII

d1 = d2
5x + 5 = 3x + 15
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5

Panjang diagonal = 5x + 5
Panjang diagonal = 5 . 5 + 5
Panjang diagonal = 25 + 5
Panang diagonal = 30 m

d1 = d2
5× + 5 = 3× + 15
5× - 3× = 15 - 5
2× = 10
x = 10/2
x = 5
Panjang diagonal = 5× + 5
panjang diagonal = 5.5 + 5
panjang diagonal = 25 + 5
panjang diagonal = 30 m
