Question

The base of an isosceles triangle is 3cm longer than each of the other sides. if the perimeter is 54cm,find the lengths of the sides​

Answer 1

Answer:

Step-by-step explanation:

Let the measure of the equal sides be 'x'

Then the base = x + 3

Perimeter = 54

x = 17 cm

∴ Length of the equal sides = 17 cm

Length of the base = 20 cm

Answer 2

Answer:

let the two isosceles sides be x

and then base would be x+3

perimeter= sum of all sides=54

So,

x+x+x+3=54

3x+3=54

3x=54-3

3x=51

x=17

hence length of sides is 17cm
