Answer:
The perimeter of the triangle is approximately equal to 18
Step-by-step explanation:
The coordinates of the vertices of the triangle are (-3, -1), (2, 3), and (5, 2)
The formula for the lengths, l, of the sides of the triangle, given their end points coordinates is presented as follows;
The lengths of the segments that make up the triangle are therefore;
Between the vertex points (-3, -1) and (2, 3), we have, √((-3 - 2)² + (-1 - 3)²) = √41
Between the vertex points (-3, -1) and (5, 2), we have, √((-3 - 5)² + (-1 - 2)²) = √73
Between the vertex points (2, 3) and (5, 2), we have, √((2 - 5)² + (3 - 2)²) = √10
Therefore;
The perimeter of the triangle = The sum of the lengths of the sides of the triangle = √41 + √73 + √10
The perimeter of the triangle = √41 + √73 + √10 ≈ 18.1094
∴ The perimeter of the triangle ≈ 18, after rounding to the nearest whole number.
Answer:
Option C.
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its perimeter is equal to the scale factor too
step 1
Find the width of the rectangle that has a length of 4 feet and a perimeter of 14 feet
The perimeter of a rectangle is equal to
substitute the values and solve for W
step 2
Find the scale factor
Let
z-----> the scale factor
To find the scale factor divide the width of the larger rectangle by the width of the smaller rectangle
so
step 3
Find the perimeter of the larger rectangle
To find the perimeter of the larger rectangle multiply the perimeter of the smaller rectangle by the scale factor
so
