Question

The area of a rectangle with width x and length 5x is 5x2. What does the coefficient 5 mean in terms of the problem?

Answer 1

The length is 5 times the width

Explanation:

Let

W ----> the width of the rectangle

L ----> the length of the rectangle

we know that

The area of rectangle is equal to

`A=LW`

In this problem we have

`L=5x` ----> equation A

`W=x` ----> equation B

substitute equation B in equation A

`L=5W`

therefore

The length is 5 times the width
