Keliling = 32
2 × (p + l) = 32
2 × (2a + 5 + 2a - 1) = 32
2 × (4a + 4) = 32
8a + 8 = 32
Menyelesaikan persamaan
8a + 8 = 32
8a = 32 - 8
8a = 24
a = 24/8
a = 3
Menentukan panjang dan lebar
panjang = 2a + 5
panjang = 2×3 + 5
panjang = 6 + 5
panjang = 11 meter
lebar = 2a - 1
lebar = 2×3 -1
lebar = 6 -1
lebar = 5 meter
