Answer:
384 cm
Step-by-step explanation:
Perimeter is the sum of all external sides. (do not mix this up with area. Perimeter is the easy one) :)
There are 4 external sides.
Top = bottom = 132 cm
Left = Right = 60 cm
Add all 4 sides:
2(132) + 2(60)
264 + 120 = 384 cm
70+75+80+90+100=415
415/5=83

The last one would be incorrect. We are looking for PART of whatever N is. Multiply by the whole number 25 is definitely not what we want to do.
Hope I helped!
Given:
The equation is
To find:
The value of b.
Solution:
We have,
Subtracting both sides by 
, we get
Therefore, the value of b is 
.
2/3 times 7 wholes is the same was 7 because 1 whole is 1.
What would you do it multiply the numerator and numerator so the would be 2x7. Then we would multiply the denominators. 3x1=1. Therefore the answer is 14/3.
