Question

The perimeter of an isosceles triangle is 24 cm the unequal side is twice as long as the equal sides
how long is the equal side =?​

Answer 1

Answer:

6 cm.

Step-by-step explanation:

Perimeter is the sum of all sides. An isosceles triangle has two equal sides and an unequal side.

Given,

Perimeter = 24cm

Equal sides = x

Unequal side = 2x

So,

x + x + 2x = 24

4x = 24

x = 24/4 = 6

Therefore,

Two equal sides = x = 6 cm

Unequal side = 2x = 12 cm
