Answer:
Area = 110.88 m²
Step-by-step explanation:
Total area = area of the two triangles + area of the rectangle
Total Area = ½bh + L*W × ½*by
= ½*7*7.2 + 7.6 × 7.2 + ½*8.6*7.2
= 25.2 + 54.72 + 30.96
Total Area = 110.88 m²
A^2+b^2= c^2
48^2+b^2= 80^2
2304+b^2= 6400
Subtract 2304 from both sides.
b^2= 4096
Find the square root.
b= 64
I hope this helps!

I think x equals 155 I may not be right but that's what I got.
Answers:
- Red = negative skew
- Yellow = symmetric
- Blue = positive skew
================================================
Explanation:
A symmetric distribution is where we have the left half be a mirror copy of the right half. In other words, we have symmetry going on.
For the yellow team, note the distance between Q1 and the median is 1 unit (47-46 = 1), and so is the distance from the median to Q3 (48-47 = 1). So the box portion has perfect symmetry. You should find that the whiskers are also perfectly symmetric as well using a similar technique of finding the distances and comparing them.
Overall, the entire box-and-whisker plot for the yellow team is perfectly symmetric.
---------------
If a distribution isn't symmetric, then it's skewed in some way. If the right side is pulled longer than the left, then we consider it "skewed to the right" aka "positively skewed". So that applies to the blue team. The red team has negative skew because its left tail is longer than the right tail.

Based on even a calculator this is the information. I made sure it is correct with the calculator.
