The answer would be 234. You will multiply 28 by 9 and minus 18.
For this case we have that the perimeter of the figure is given by the sum of the lengths of the sides, that is:
Thus, the perimeter of the figure is 64 centimeters.
Now, we find the area of the figure:
We have that by definition, the area of a rectangle is given by:
Where:
a and b are the sides of the rectangle
We have 4 vertical rectangles from left to right:
Thus, the total area is
Answer:
The perimeter of the figure is 64 centimeters.
Answer:
The formula T= 10d +20
A) what does each term on the right side of the equation represent?
- 10d⇒ 10 degrees increase per 1 km and 20 deg surface temperature
B) Estimate the depth where the temperature is 60 degrees C.
C) What is the approximate temperature at a depth of 4km?
26x3=78
78-x=72
x=6
