Question

4. The perimeter of an isosceles triangle is 10- cm. If one of its equal sides is 2 cm, find the third side.
​

Answer 1

Answer:

6cm

Step-by-step explanation:

PERIMETER IS SUM OF 3 SIDES

SO, 2+2+X=10cm

SO, THIRD SIDE IS 6cm

Answer 2

$\star$ANSWER

$\bullet$ Your Answer Is 6 cm.

$\star$ Explanation:-

Given:-

• The perimeter of an isosceles triangle =  10 cm.

• The length of equal sides = 2 cm.

To Find:-

• The length of third side.

• So let the third side be x.

Formula Used:-

$\implies$ Perimeter of a triangle,

= Sum of all its three Sides.

So ATQ:-

$\implies$Perimeter of the given triangle = 10 cm.

And the length of its two equal sides = 2 cm.

Now, lets find out the third side by applying the above formula:-

$\\\tt\mapsto 2 cm+2 cm+x = 10 cm. \\ \\ \tt\mapsto 4 cm+x = 10 cm.\\ \\ \tt\mapsto x = 10 cm-4 cm. \\ \\ \tt\large\mapsto{\fbox\red{\fbox{ x = 6cm.}}}$

SO,

We have got the value of x which is equal to 6 cm.

Therefore the third side = 6 cm.
