Answer:
AE=22.4
Step-by-step explanation:
BE is 1/2 of BC
BC is 20 cm                 All sides of a square are equal
BE = 1/2 BC                  Property of a midpoint.
BE = 10
Now just use Pythagorus
AB^2 + BE^2 = AE^2
AE^2 = 20^2 + 10^2   Perform the sqrs
AE^2 = 400 + 100      Add the terms
AE^2 = 500                Take the square root of both sides
√AE^2 = √500
AE = 22.36
AE ≈ 22.4

In order to write 

 as a percentage, we must first convert the fraction into a decimal. We can do that simply by dividing.
35 / 20 = 1.75
In order to convert a fraction to a decimal, we must multiply it by 100
1.75 * 100 = 175%

 as a percentage is 175%.
Hope that helped =)
