w represents width
4w represents length
d represents diagonal
w2 + (4w)2 = d2
w2 + 16w2 = d2
17w2 = d2
±w√17 = d
The diagonal is the width times √17.
You need to multiple 7 and 5 or you could just skip the answer
The gcf is 3 the lcm is 48 :^)
You should try to add 4 and place the 2 in the 3 digit slot
