The area of a triangle is given by one-half base times height. So...
56 = 0.5bh
We can divide both sides by 0.5 to isolate the bh...
112 = bh
Now to find all the possible combinations for the base and height, we need to find the factors of 112. They are 1, 2, 4, 7, 8, 14, 16, 28, 56, 112.
So the possible sets are:
1 and 112
2 and 56
4 and 28
7 and 16
8 and 14
Hope this helps :)

Answer:
181.12 mm²
Step-by-step explanation:
12.8 x 28.3 = 362.24
362.24 ÷ 2 = 181.12
Answer:
+/- 1.9983
Step-by-step explanation:
The critical values for a confidence interval for the population mean, with population standard deviation not known, are obtained from the student's t distribution.
The sample size is given as 64. The degrees of freedom will thus be;
sample size - 1 = 64 - 1 = 63
The confidence level is given as 95%. The level of significance will thus be;
100 - 95 = 5%.
The area in the right-tail will thus be 2.5%. Therefore, we looking for a t-value such that the area to its right is 2.5% and the degrees of freedom being 63. From the t-tables we have;
+/- 1.9983
