Answer:
the answer is 108.
Step-by-step explanation:
the answer is 108
9.2 x 13.8 = 126.96, now usually to get the area of a triangle we would half this but because we have two of the same triangle we would then have to double it again so they cancel each other out. We then do 6.9 x 9.2 which equals 63.48 and again we have two of the same triangle so no need to half it. So we add the two totals of 126.96 and 63.48 together to get 190.44.

Answer:
15.24 square meters
Step-by-step explanation:
Signal range of baby monitor is 50 meter radius.
The baby monitor will therefore cover an entire area of 50 meter radius.
Formula for finding the area of a circle is = π r 2 = π X r X r
Meaning: π = 3.142, r = radius of signal monitor
Therefore Area of circle = Square meters of coverage of baby monitor = 3.142 X 50 meters X 50 meters = 157.14 m2 (157.14 meters squared)

Answer: 3253
Step-by-step explanation:
Given : A test requires that you answer either part A or part B.
Part A consists of 7 true-false questions.
i.e. there are 2 choices to answer each question.
Now, the number of ways to answer Part A : (1)
Part B consists of 5 multiple-choice questions with one correct answer out of five.
i.e. there are 5 choices to answer each question.
Now, the number of ways to answer Part B : (2)
Now, the number of different ways to completed answer sheets are possible= [Add (1) and (2) ]
