Question

40.
The perimeter of a triangle is 12 cm. If
all the three sides have lengths (in
cm), in integers, then how many such
different triangles are possible?
(1) 2
(2) 3
(3)
4
(4) 5​

Answer 1

Answer:

The smallest integer larger than the perimeter = 41

Step-by-step explanation:

We have been Given Two sides of a triangle

10 & 20 units

We need to find smallest integer larger than perimeter

hence we would like to have a triangle with least Perimeter

as We know Sum of Two sides > Third Side

=> unknown Side + 10 > 20

=> unknown Side > 10

Hence perimetr > 10 + 10 + 20

=> Perimeter > 40

The smallest integer larger than the perimeter = 41
