Question

The length of each of the legs of an isosceles triangle is 3 km longer than the base. The perimeter of the triangle is 24 km. How do you find the length of each side?

Answer 1

6-9-9

Explanation:

Let `x` be the length of the base
`=> x+3 =` length of the legs

`x + x+3 + x+3= 24`

`=> 3x + 6 = 24`

`=> 3x = 18`

`=> x = 6`

`=> x + 3 = 9`
