Answer:
392 ft²
Step-by-step explanation:
Break this area into two parts, that is, into two trapezoids. The first trapezoid, on the left, has length 8 ft and average length (30 ft + 27 ft)/2, so its area is (8 ft)(28.5 ft) = 228 ft ².
The second trapezoid has width 8 ft and average length (19 + 22)/2 ft, or 8 ft by 20.5 ft). The area of this part is 164 ft².
Thus, the total area is 164 ft² + 228 ft², or 392 ft²

Answer:
At 2:00 there will be 38,400 bacteria.
Step-by-step explanation:
600/150 = 4
2400/600 = 4
So, the bacteria quadruples every half hour.
At 1:30, there will be 2400*4 = 9600.
At 2:00, there will be 9600*4= 38400
