Answer:
40 cm
Step-by-step explanation:
Step one:
Given data
Diagonal = 50cm
If the length on one of the sides is 30cm
Then applying Pythagoras theorem we can find the other side as
Step two:
[tex]d^2= l^2+w^2\\\\50^2= 30^2+w^2\\\\2500=900+w^2\\\\2500-900= w^2\\\\1600=w^2\\\\[/tex]
square both sides we have
w= √1600
w= 40 cm
