Question

the length of two sides of a triangle are 65cm and 16 cm what can be the third side​

Answer 1

Answer:

Area of triangle with sides a, b,and c and s =  

2

a+b+c

​  

 is  

s(s−a)(s−b)(s−c)

​  

 .

For triangle with sides 16 cm, 12 cm and 20 cm, s=  

2

16+12+20

​  

=24cm  

Area of the triangle with sides 16 cm, 12 cm and 20 cm =  

24(24−16)(24−12)(24−20)

​  

=  

24×8×12×4

​  

=  

8×3×8×4×3×4

​  

=8×3×4=96cm

Area of triangle  can also be calculated using the formula

1

​  

×base×height

Let the height for base 12cm, be h.

So, area =

​  

×12×h=96cm

=>h=16cm

Answer 2

Answer:

Between 0 and 81 cm.

Step-by-step explanation:

The sum of any two sides of a triangle is more than the third side.

So, the sum of two sides = 65 + 16 cm = 81 cm

So, the third side has to be less than 81 cm and more than 0 cm or Between 0 and 81
