The temperature in a greenhouse should be 66 degrees or higher. One​ morning, the heater stopped working. The temperature dropped 4 degrees before someone fixed the heater. The temperature was still at least 66 degrees when the heater started working again. How can you best describe the temperature in the greenhouse before the heater stopped​ working?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
