Question

The length of three sides of a triangle are 10 1 upon 2 cm 12 3 upon 4 cm and 9 2 upon 3 cm what is the perimeter of the triangle​

Answer 1

Answer:

3792/12cm  OR  316cm

Step-by-step explain :

First learn the formula of perimeter of triangle which is Sum of all sides.

Then write everything in fractional form as it is. Then make the denominator equal by the method of LCM . Here the LCM is 12. Then multiply the numerator with the number that you had obtained after taking the LCM.

When the denominator become same then add all three terms(A. of Triangle). Then  the answer will come 3792/12cm in fractional form and 361cm in integer form. And  the unit must be there.
