Hello!
<h2>Answer:</h2>We already know that the formula for area of a rectangle is A = l × w.
Notice how the width and the length are being multiplied to find the area.
Well, to find the width, we must do the <em>opposite</em> of multiplication, which is division.
Since we already have the length, all we have to do is divide the area by the length for each of the questions.
1:
A = l × w
55.5 = 9.25 × w
= 6
2:
A = l × w
48.75 = 7.5 × w
= 6.5
3:
A = l × w
44 = 5 × w
= 8.8
4:
A = l × w
31.25 = 5 × w
= 6.25
