Explanation:
Food security is a measure to check the availability of food to individuals and their affordability being a prime factor. In other terms, it means that everyone has a sufficient amount of health food i.e it can be measured by calorie intake per person to lead healthy lives.
Food availability in developing countries is cause and an effect of several factors like poverty, status, political stability and infrastructure etc. Most of developing countries in the world have an undernourished or are malnourished population . Mostly in the African countries and the Asian countries like Afghanistan, Domenico republic of congo and Mexico which is dealing with acute food insecurity. As compared to developed countries like in Australia and North America have low food insecurity but they still face global water crisis, land degradation and impact of climate change along with food wastages.
Programs that help developing countries reach food security goals.
Use of genetically modified crops.
Boosting agricultural science and giving agricultural insurance.
Making food security gender-equal.
Reducing land-use changes.

Given:
Similar triangles ABC and PQR with AB = 4 and PQ = 7.
To find:
The scale factor, ratio of perimeters, and ratio of areas.
Solution:
In similar figures the scale factor is the ratio of side or image and corresponding side of original figure.
In similar triangles ABC and PQR, the scale factor is
The scale factor of triangle ABC to triangle PQR is 
.
The ratio of the perimeters of similar triangles is equal to the ratio of their corresponding sides.
The ratio of the perimeters is 4:7.
The ratio of the areas of similar triangles is equal to the ratio of squares of their corresponding sides.
Therefore, the ratio of the areas is 16:49.
