The lengths of the sides of the triangle are 15 cm, 17 cm and 13 cm. Find the perimeter of the triangle, the length of which is 2 times the lengths of the sides of the given triangle.
To solve the problem, we first find the doubled lengths of each side of the triangle.
To do this, we multiply the known values by 2 in turn.
In this case, we get:
15 * 2 = 30 cm.
17 * 2 = 34 cm.
13 cm * 2 = 26 cm.
In order to determine the perimeter of any triangle, you must use the following formula:
P = a * b * c.
Where, P is the perimeter of the rectangle.
a, b, c – sides of the rectangle.
Substituting these numerical values into the formula, we get:
P = 30 + 34 + 26 = 90 cm.
The perimeter of this triangle is 90 centimeters.
