а=7 см

б=х=б1+б2+б3

2+2+2=6

б=6 см

а1+а2+а3=х=7:3

7:3=2,1

а1=1см+а2=3см+а3=3=7см

Р=а+б+а1+а2+а3+б1+б2+б3=7+6+1+3+3+2+2+2=26 см

Объяснение:

обозначим все стороны буквами а и б. чтобы найти б сторону добавляем все стороны б1,б2,б3. чтобы найти стороны а1,а2,а3 делим 7 на все стороны то сесть на 3.
