Question

Each of the congruent sides of isosceles triangle is 3 times the
Base if perimeter of the triangle is 28cm find the length of each side

Answer 1

Answer:

hi how are you i am fine and hope you will also be fine there

Answer 2

Answer:

As you know that perimeter of triangle is the sum of all sides.

Let us consider the base to  be x.  So

We will add the base and both congruent sides of the triangle.

As mentioned in the question  the congruent sides of triangle are 3 x  (because the congruent side of triangle are three times of the base)

Step 1:  x + 3 x +3 x = 28

Step 2: 7 x = 28

Step 3: x = 28/7

Step 4: x = 4 cm(Because perimeter is given in cm)

Verification :   x = 4;  3 x = 12 . So

4 + 12 + 12 = 28

28 = 28

L.H.S = R.H.S

Hence verified

I HOPE THIS WAS CLEAR TO YOU AND IF YOU LEARNT SOMETHING NEW THEN MARK  THE BRAINLY OPTION .
