Answer:
AE Measure: 23.36 units
Step-by-step 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
Repeat effort :-)
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
