Answer 1

Explanation:

As ABCD is a square , BC = 20 cm

BE = 20/2 = 10 cm

Also , angle B = 90⁰

By pythagoras theorem :

AE² = 20² + 10²

AE² = 400 + 100

AE² = 500

AE = 10√5 cm

Answer 2

AE Measure: 23.36 units

Explanation:

BA: 20cm

BC:20cm

BE:10cm CE: 10cm

a^2 +b^2=c^2

BE^2 +BA^2 = AE^2

√100 + √400 = √500

AE^2 = √500 = 23.36

AE = 23.36 unit
