Answer 1

Бічна =56+9=65
P=56+65+65
P=186

Answer 2

Finding the Perimeter of an Isosceles Triangle

To find the perimeter of the isosceles triangle, we can use the given information that the base of the triangle is 56 cm and the length of the lateral side is 9 cm longer than the base.

Calculating the Perimeter

The perimeter of a triangle is the sum of the lengths of its three sides. In the case of an isosceles triangle, where two sides are equal, the perimeter can be calculated using the formula: Perimeter = Base + 2 * Lateral Side

Given: - Base = 56 cm - Lateral Side = Base + 9 cm

Substitute the Values

Substitute the given values into the formula to find the perimeter: Perimeter = 56 + 2 * (56 + 9)

Solving for the Perimeter

Let's calculate the perimeter: Perimeter = 56 + 2 * 65 Perimeter = 56 + 130 Perimeter = 186 cm

So, the perimeter of the given isosceles triangle is 186 cm.
