Question

The perimeter of an isosceles triangle is 14 cm. If each of the equal sides is 5 cm, then what is the length of its base?​

Answer 1

Answer:

4cm

Step-by-step explanation:

Let the base be x,

Therefore,

Perimeter of triangle = side + side + side

14 = 5 + 5 + x

14 = 10 + x

14 - 10 = x

x = 4cm

Therefore, base = 4cm

Answer 2

Answer:

4cm

Step-by-step explanation:

Let the base be x,

Therefore,

Perimeter of triangle = side + side + side

14 = 5 + 5 + x

14 = 10 + x

14 - 10 = x

x = 4cm

Therefore, base = 4cm
