Ricky want so make a square patio in his yard. He has enough concrete to pave an area of 141 square feet. If A represents the area of the patio, and s represents the side length of the patio, use the formula s = √ A to find the length of each side of his patio. Round your answer to the nearest tenth of a foot.

An Ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.
