By definition, the perimeter of the triangle is the sum of its sides.
We must then use the formula of distance between points:
We now look for the longitus for each of the sides:
For L1:
For L2:
For L3:
Then, the perimeter is given by:
P = L1 + L2 + L3
Substituting values we have:
Answer:
the perimeter of triangle ABC is:
none of the above.
Answer:
Step-by-step explanation:
12<18/3(-2)+12 turns into 12<18/-6+12
False
Answer:
The length of the rectangle is 37 yards, and the width of the rectangle is 17 yards.
Step-by-step explanation:
Given that the length of a rectangle is 3 yards more than twice the width, and the area of the rectangle is 54 yards, the following calculation must be performed to find the dimensions of the rectangle, knowing that the area of a rectangle arises from multiplying its base by its height:
2X + 3 + X = 54
3X + 3 = 54
3X = 54 - 3
X = 51/3
X = 17
(17 x 2) + 3 = 37
Therefore, the length of the rectangle is 37 yards, and the width of the rectangle is 17 yards.
Answer:
--- You
--- Another student
Reason: Because there is a variation in the given dimensions
Step-by-step explanation:
Given
Your measurement
Another students'
Solving (a): The area
Area is calculated as:
For you
For the other student
Solving (b): Reason for the variation in the areas
The given measurements are estimates of the dimensions of the rectangle.
Since there is a variation in the estimates, there will be some level of variation in the calculated area.
Combine like terms
8u+3u= 11u
and
9v-5v= 4v
So the answer is 11u+4v
