Question

The two side of a triangle are 14 units and 12 units. The perimeter of the triangle is 36 units. What is the third side unit

Answer 1

Answer:

Given

1st Side = 14

2nd Side = 12

Step-by-step explanation:

1st Side + 2nd Side + 3rd Side =. Perimeter of Triangle

Let

1st Side = 14

2nd Side = 12

3rd Side. = X

Perimeter = 36

1st Side + 2nd Side + 3rd Side =. Perimeter of Triangle

14+12+X= 36

26 + X = 36

X =. 36-26

X. = 10

Then The Third Side is 10 Units

Let the length of the third side be x cm.

The length of the other two sides is 12 cm and 14 cm.

Now, the Perimeter of triangle = 36 cm
