Question

Периметр равнобедренного треугольника равен 7,5 м а Боковая сторона равна 2м Найдите основание

Answer 1

У равнобедренного треугольника 2 стороны равны, значит 
7,5 - (2+2) = 3,5

Answer 2

Perimeter of an Isosceles Triangle

To find the base of an isosceles triangle when the perimeter is 7.5 m and one of the equal sides is 2 m, we can use the formula for the perimeter of an isosceles triangle.

The perimeter of an isosceles triangle is given by the formula:

Perimeter = 2 * Side + Base

Given that one of the equal sides is 2 m and the perimeter is 7.5 m, we can substitute these values into the formula and solve for the base.

Let's calculate the base:

Perimeter = 2 * Side + Base

7.5 m = 2 * 2 m + Base

7.5 m = 4 m + Base

Subtracting 4 m from both sides:

7.5 m - 4 m = Base

3.5 m = Base

Therefore, the base of the isosceles triangle is 3.5 m.
