Answer:
48
Step-by-step explanation:
The mean of a number is the sum of all the numbers divided by how many numbers there are. We can set up this formula: .
When we plug our values into this equation, we get: . Solving this equation gets us sum = 6 * 8 = 48
The area of the considered triangle RST is given by: Option A: 9 sq. units.
<h3>How to find the area of a triangle?</h3>If we have:
Then we get:
Area of a triangle =
The missing image is attached below.
If we take the base of the triangle as RS, then as the line UT is perpendicular to RS (as RS is parallel to x axis and UT is parallel to y axis) and touching from the base line RS to T, thus, it can be taken as height.
Thus, we have:
Area of RST = half of length of RS (base) times length of UT (height)
As visible from image, we have:
Length of RS = 6 blocks of unit length = 6 units
Similarly, length of UT = 3 units
Thus, we get:
Area of RST =
Thus, the area of the considered triangle RST is given by: Option A: 9 sq. units.
