Answer:
The new perimeter is 1400 cm
Step-by-step explanation:
The perimeter of the bedspread is the perimeter of a rectangle, whose formula is:
Perimeter = 2 * width + 2 * length
Then the perimeter of the initial bed spread is:
Perimeter = 2 * (238 cm) + 2 * (435 cm) = 1346 cm
as you calculated.
Now, she gets a new bedspread that is 27 cm longer. So the new dimensions are 238 cm width, and (435 + 27) cm length, then the perimeter becomes:
Perimeter = 2 * (238 cm) + 2 * (462cm) = 1400 cm

The gain percentage is given by
To determine the extent of how many times greater is the
number of bacteria in petri dish A than petri dish B, we simply have to take the
ratio of the two.
1.75 x 10^18 / 6.25 x 10^15 = 280
So the bacteria in petri dish A is 280 times larger.
