Answer:
5cm
Step-by-step explanation:
- In order to find the area of a 2d regular shape such as a square, you need to do length × width = area
- A square has four regular sides, which means they must all be the same length, which in turn means that we only need to find one number, and it must be the square root of 25.
So, the length of each side is 5cm.

13/15 7/9 4/5 2/3 in that order.
For this case you can see the problem like a triangle with a right angle (90 degrees), an angle of 45 degrees and a hypotenuse of 100 feet.
Then, the vertical height above the point where the rope is held is
y = 100 * sin (45) = 70.71 ft
The answer is
the kite vertically above the point at which the string is being held is 70.71 ft high
