Calculate Triangle ABC Perimeter: Given Side Lengths 10, 5.6, and 4

Question

Find the perimeter of the triangle ABC

00:00 Determine the perimeter of the triangle

00:03 The perimeter of the triangle equals the sum of its sides

00:07 Substitute in the relevant values according to the given data and solve for the perimeter

00:12 This is the solution

The problem requires us to calculate the perimeter of triangle ABC with given side lengths. To solve this:

Step 1: Identify the given side lengths
According to the given information:
$AB = 10$
$BC = 5.6$
$CA = 4$
Step 2: Apply the perimeter formula
The formula for the perimeter $P$ of a triangle is: $P = AB + BC + CA$
Step 3: Perform the calculation
Plugging in the values, $P = 10 + 5.6 + 4 = 19.6$

Therefore, the perimeter of triangle ABC is $19.6$ .
