Answer:

61.08m

Step-by-step explanation:

Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:

  • l = 65m
  • θ = 70°

As you can see, there has been made a right angle triangle. So:

sin70 =  \frac{h}{l}  \\ h = l \times sin70 \\ h = 65 \times 0.9397 = 61.08 \\ h = 61.08

So the kite is approximately 61.08m above the ground.

In order to find the sin70° i used a calculator.

pav-90 [236]
A=LW,

W=L/2, L=2W so:

A=(2W)W

A=2W^2 and A=34 so:

2W^2=34

W^2=17

W=√17, and since L=2W

L=2√17

So the length is 2√17 and the width is √17

(length≈8.25 and width≈4.12 if you wanted approximations...)
