In order to answer this problem, we need to find a combination of length and width that would have an area of 65 feet^2 and 36 feet. So far, we know that 65=l*w and 36=2l+2w. The answer is the length is 5 and the width is 13. We can check our work.
5*13=65
2(5)+2(13)=10+26=36
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis
Tectonic plates are parts (pieces) of the outermost layer of Earth: the Crust. (the outermost part of the mantle is also often included in the plates). This means that the land in the middle of the plates is relatively stable while the borders of the plates can be in movement - after all this is where two pieces meet. Plate borders are where the vocanoes and Earthquakes often take place.
Let's say that the land has pollution meaning there is trash everywhere and dead plants over there, with those types of pollution it will harm our water supply because sometimes the pollution can affect our water.
Clearing the lands that has pollution can do good for our water and our ecosystem. When we clean the lands, more plants are able to grow, animals build their homes there, etc. That means that the animals and/or plants have a drinking water that is safe to drink and isn't polluted because we cleaned the land and the water.
Keep America clean.
Hope this helped :)
Have a great day
