Question

The perimeter of a triangle is 19cm and its two sides are 8m and 7m. Find its third side? Plz solve it as soon as possible.

Answer 1

Heya mate,
Here is your answer,

perimeter of the triangle = 19m
1st side = 8m
2nd side = 7m

1st side + 2nd aide +3rd side = perimeter
=> 8 + 7 + 3rd side = 19
=> 15 + 3rd side = 19
=> 3rd side = 19-15 = 4m

Hence the 3rd side is 4m.
