Question

The area of a rectangle with width x and length 7x is 7x2. What does the coefficient 7 mean in terms of the problem?

Answer 1

Answer:

7 is number of times length is longer than the width, x.

Step-by-step explanation:

The area of a rectangle with width x and length 7x is $7x^2$.

The area of the rectangle is $length\times width$

Here width is x and the length is 7x. This means the length is 7 times width.

And the area is a $7x^2$ means 7 is number of times length is longer than the width, x.

Like, if x = 3

Then $7x=7\times3=21$

Answer 2

Length is 7 times the width
