Answer:
D. the length is 6 times the width
Step-by-step explanation:
The area of a rectangle is given by the formula
Area = Width x Length
If a rectangle has width x and length 6x then the area is x * 6x = 6x²
Since we have length = 6x and width = x it is clear that length = 6 times width because for any value of x which represents width the length will be 6 times that value
For example if we choose x = 10 that means width = 10 then length = 6x
= 6 x 10 = 60 which is 6 times the width
