Question

If the perimeter of the triangle is 15 cm and any two sides are of length 4 cm and 3 cm, then find the length of the third side ?

Answer 1

Step-by-step explanation:

This question is wrong. There can be no triangle with side 3 and 4 cm and perimeter 15 cm. Because sum of two sides is always greater than the third side but here the sum 7 is smaller.

Answer 2

Answer:

here, as we don't know which kind of triangle it is so we will assume it as scalene triangle

now, lets take the 3rd side as x

perimeter  = side + side + side

             15           = 3+4+x

              15-7=x

              8cm is the length of the 3rd side

hope it helps :)
