Question

In an isosceles traingle one side is three more than two equal sides and its perimeter is 24cm. Then find the three sides

Answer 1

which class you are please tell me

Answer 2

Answer:

Let the two equal side be X,

So other side be 3+X,

Perimeter of Triangle = 2A+B. ( where A is equal side )

Perimeter of Triangle= 2X +3+X

24cm=3X+3

24cm=3(X+1)

24/3=X+1

8=X+1

8-1=X

X=7

Two equal sides are 7cm and 7cm

the other side = 3+X

= 3+7

= 10cm
