Answer 1

Answer:

24 will be the answer.

hope its help u

Answer 2

Let we name the yellow triangle as Δ ABC.

according to the question, AB = 14 cm, BC = 8 cm,

now we have to find out AC = ?

using Pythagoras formula  we can get  AC,

AC² = AB² + BC²

AC² =(  14)² +( 8 )²= 260

AC =√260= 16

∴AC will be 16 cm.

now we have to find out the perimeter of  ΔABC.

perimeter of a Δ = some of 3 sides,

perimeter of  ΔABC=(AB + BC + AC )cm.

                                  =( 14+ 8+ 16) cm

                                  = 38 cm.

Ans :- perimeter of yellow triangle will be 38 cm.
