Question

Здравствуйте, помогите пожалуйста)))

Answer 1

1 столбик
B=3
P=6/2*2+6*2=18
S=6/2*6=18
2 столбик
B=2
P=4/2*2+4*2=12
S=4/2*4=8
3 столбик
B=4
P=8/2*2+8*2=8+16=24
S=8/2*8=32

Answer 2

$a = 6 \: \: \: b = 6 \div 2 = 3 \\ p = (a + b) \times 2 = (6 + 3) \times 2 = 18 \\ s = a \times b = 6 \times 3 = 18$
$a = 4 \: \: b = 2 \\ p = (4 + 2) \times 2 = 12 \\ s = 4 \times 2 = 8$
$a = 8 \: \: b = 4 \\ p = (8 + 4) \times 2 = 24 \\ s = 8 \times 4 = 32$
