Question

Two side of a triangle
are 10 cm and 12 cm . the
perimeter of the triangle is 35 cm. What is the third side ​

Answer 1

Answer:

The perimeter of a triangle is 35 cm

The length of its two sides are 10 , 12 cm

so, let the other length of the triangle be x

we know,

The perimeter of a triangle is = sum of all sides.

ATQ

10 + 12 + x = 35

22 +x = 35

x = 35 - 22

x = 13

So , the length of the third side is 13 CM

Answer 2

GIVEN:

Measure of the two Sides of the Triangle = 10cm, 12cm

Perimeter of the Triangle = 35cm

TO FIND:

The Measure of the 3rd Side of the Triangle

SOLUTION: ⭐

Let the 3rd Side of the Triangle be x

Perimeter of a Triangle = Sum of the three Sides [a + a + a]

$35 = 10 + 12 + x \\ = > 35 = 22 + x \\ 35 - 22 = x \\ 13 = x$

VERIFICATION:

$35 = 10 + 12 + 13 \\ 35 = 35$

THEREFORE, It is Verified that LHS is Equal to RHS.

CONCLUSION:

The Measure of the 3rd Side of the Triangle is 13cm
