Hello!
The formula for finding area is l × w
If the area is 19 ½ inches and it was 3 ¼ inches wide, then the length will be 19 ½ ÷ 3 ¼ (Area ÷ Width)

Change both to improper fraction



Keep 39/2
Change ÷ to ×
Flip 13/4 = 4/13



solve for "a", once you get "a", plug it back into either equation to get "b"
54 rounded to the nearest 10 would be 50 because 54 is closer to 50 than 60.
So, the answer is 50.
Hope it helps
