Question

the perimeter of a triangle is 14 cm. the second side of the triangle is 5 cms less than the first side and the third side is 3 cm more than 2nd side

Answer 1

Let the fist side be x

Then second side will be x-5

Third side will be x-5+3 =x-2

Perimeter =14cm

x+x-5+x-2=14

3x-7=14

3x=21

x=7

So fist side is 7cm

Second side is 2cm

And third side is 5cm

Hope it helped you

Answer 2

Let the first side be X .
Now second side is X-5.
And third side is X-5+3
= X-2
Perimeter = first +second+third
14=X+X-5+X-2
14 =3X-7
14+7=3X
21=3X
21÷3=X
7=X
First side=7
Second side =X-5
=7-5
=2
Third side = X-2
=7-2
=5
