Пошаговое объяснение:
поскольку длины сторон - целые числа и задача расчитана на 6 класс, начнем перебор:
между прочим, минимальное целое положительное (отрциатлеьных сторон не бываеет) число - это 1
пусть ширина 1, тогда длина 1+9=10, площадь 1*10=10
пусть ширина 2, тогда длина 2+9=11, площадь 2*11=22
пусть ширина 3, тогда длина 3+9=12, площадь 3*12=36
пусть ширина 4, тогда длина 4+9=13, площадь 4*13=52
пусть ширина 5, тогда длина 5+9=14, площадь 5*14=70
пусть ширина 6, тогда длина 6+9=15, площадь 6*15=90 - то что надо
периметр = 2*(6+15)=2*21=42 (см)
ответ: 42
