Answer:10
Step-by-step explanation:
by pythagoras theorem
if ABCD is a rectangle such that AB =CD and BC=AD and AC & BD as diagonals
then,
(AB)square + (AD) square = (AC) square
as per question
let AB=CD=8cm
BC=AD=6cm
then
by pythagoras theorem
(8) sqsuare + (6) square = (AC) square
64 + 36 = (AC) square
100 = (AC) square
10 = (AC)
therfore
lenght of diagonal AC is 10 cm
