Ответ:

36 см

Пошаговое объяснение:

Середні лінії трикутника дорівнюють половині сторін, до яких вони паралельні.

Сума середніх ліній 4+6+8=18 см, отже периметр шуканого трикутника Р=18*2=36 см.

Five Ways to Reach a Healthy Weight
A. Watch out for portion distortion.

C. Don't skip breakfast.
D. Reduce screen time.
E. Exercise.
F. Don’t chat on the Net.
G. Eat 5 servings of fruits and veggies a day.
1. ___________________. Regular physical activity burns calories and builds
muscle — both of which help you look and feel good and keep weight off. Walking
the family dog, cycling to school, and doing other things that increase your daily
level of activity can all make a difference. If you want to burn more calories,
increase the intensity of your workout and add some strength exercises to build
muscle. The more muscle you have, the more calories you burn, even when you
aren't exercising.
2. ___________________. Fruits and veggies are about more than just vitamins and
minerals. They're also packed with fibre, which means they fill you up. And when
you fill up on fruits and veggies, you're less likely to overeat when it comes to high
calorie foods like chips
3. ___________________. Serving sizes have increased over the past 10 years,
and these extra calories contribute to obesity. Another key factor in weight gain is
that more people drink sugary beverages, such as sodas, juice drinks, and sports
drinks. So choose smaller portions (or share restaurant portions) and go for water or
low-fat milk instead of soda.
4. ___________________. One reason people get less exercise these days is
because of an increase in "screen time" — the amount of time spent watching TV,
looking at the computer, or playing video games. Limit recreational screen time to
less than 2 hours per day. If you're with friends at the mall, you're getting more
exercise than if you're IMing them from your room.
5. ___________________. Breakfast kick-starts your metabolism, burning
calories from the get-go and giving you energy to do more during the day. People
who skip breakfast often feel so hungry that they eat more later on. So they get more
calories than they would have if they ate breakfast. In fact, people who skip
breakfast tend to have higher BMIs than people who eat breakfast.
