Question

the perimeter of isoscles triangle is 30cm and measure of shortest side is 4cm what is the length of longest side plz answer ​

Answer 1

Answer:

In an isosceles triangle two sides are of equal length

we are given perimeter and third side,

let the unknown sides be x

30 = 4 + x + x

30 = 4 + 2x

2x = 30 - 4

x = 26 / 2

x = 13 cm

so the longest side length is 13 cm.
