Answer 1

Answer:

3+5+a=21cm

Step-by-step explanation:

Answer 2

The third side of RED is 56.31

Step-by-step explanation:

Here in the question it is given that the two similar triangles have the ratio of their perimeter as 16:49.

Let the third side of the triangle RED is X.

So, here we are given with the perimeter of SKY as 21cm.

Then the perimeter of RED will be =3+5+X=(8+x)

Then, 21/(8+X)=16/49

⇒X=56.31(answer)
