Answer:
perimeter = sum of all sides. this is same for polygons
rect: area l×b. peri = 2(l+b)
Step-by-step explanation:
15+5 = 20
20*2 = 40 cm is the perimeter of the given figure
10. The numbers on the horizontal line would be:
1, 2, 3, 4, 5, 6
11. Count how many of each number there is.
1- 3
2- 4
3- 2
4- 3
5- 2
6- 2
So numbers 1 and 4 will both have 3 dots above them and numbers 3, 5, 6 will have 2 dots above them.
Answer:
ex.: 71 (see explanation)
Step-by-step explanation:
The answers on this could vary. An acute angle is an angle less than 90 degrees. However, you also have to remember that a triangle adds up to 180 degrees, so the angle cannot be so small that the third angle would be over 90. For my answer, I subtracted 38 from 180 (the whole triangle) and then divided by 2.
I hope this helps.
