Question

8. The perimeter of an isosceles triangle is 55 cm. Each of the equal sides is
two times the third side. Find the lengths of all sides ​

Answer 1

♦let the length of the third side be X

♦length of other sides = 2x

♦perimeter of the triangle = 55 ( given)

sum of all sides of triangle = 55

2x + 2x + X = 55

5x = 55

X = 55 / 5

X = 11cm

♦1st side = 2 X = 2 × 11 = 22cm

♦2nd side = 2x = 2 × 11 = 22cm

♦3rd side = X = 11cm

hope it helps you............

Answer 2

answer

third side 11 ,equal side 22

Step-by-step explanation:

let third side x

equal side 2x

perimeter = x+2x+2x=55

5x=55

x=11 ,2x =22
