I had that same answer, its on google just search it up.
Answer: 40 cm
Step-by-step explanation:
Area = length x width
A square has 4 equal sides so length = width (they have to be the same number)
10cm x 10cm = 100cm^2 or the square root of 100cm^2 = 10cm
10cm x 4 sides = 40cm
To find x, you figure out which ratio would be easiest to use.The cosine of the angle (22*) would be x/ll, since cosine is adjacent leg/hypotenuse. Type into a graphing calculator: 11cos(22)
The answer is 10.2. Make sure your calculator is in degree mode!
