Question

The perimeter of triangle is 38 cm, AB=AC and L(AB)=AC and L (AB) greater than L( BC) by 7 cm. find the length of sides of triangle ABC. ​

Answer 1

Answer:14.6, 14.6 ,22.4

Step-by-step explanation:It is given that l (AB)=l (AC) and l (AB)=l (BC)+7

and the length of the perimeter is 38 cm

Now,

L (AB)+L (AC)+L (BC)= 37

L (AB)+ L (AB) + L(AB)-7=37

3×L (AB)=44

L (AB)=44÷3

L (AB)=L (AC)=14.6

L (BC)=22.4
