A rectangle has area 48 and width 6. What is its length?

Explanation:
Area of a rectangle is found by multiplying length by width. With a width of 6 and an area of 48, the length must be 48 ÷ 6 = 8. So the length is 8, since 8 × 6 = 48. If the length were 6, 6 × 6 would be 36; if it were 12, 12 × 6 would be 72; if it were 16, 16 × 6 would be 96. Only 8 gives the correct area.
