If a rectangle has length 9 and area 63, what is the width?

Explanation:
A rectangle's area is found by multiplying its length by its width. With a length of 9 and an area of 63, you can find the width by dividing the area by the length: width = 63 ÷ 9 = 7. So the width is 7. Check: 9 × 7 = 63, which matches the given area. If the width were 9, the area would be 81; if it were 6, the area would be 54; if it were 14, the area would be 126. Only 7 gives the correct area.
