Area formula of a parallelogram is
A = base x height
Given are the
Area = 60 m² and base = 10 m
Substitute the given:
60 = 10h (divide by 10 to find value of h)
(10 and 10 cancels out)
h = 6
The height of a parallelogram with a base of 10m and an area of 60m² is 6m

Answer:
The width is
Step-by-step explanation:
From the question we are told that
The population standard deviation is
The sample size is
The sample mean is
Given that the confidence level is 99% then the level of significance is mathematically represented as
=>
=>
Next we obtain the critical value of from the normal distribution table, the value is
Generally margin of error is mathematically represented as
substituting values
The width of the 99% confidence interval is mathematically evaluated as
substituting values
