Question

The length of a flowerbed is 4 times as long as its width. If the width is 3/8 meter, what is the area?

Answer 1

3/4 = 0.75 (width)
0.75 * 4 = 3 (width * 4 = length)
3 * 075 = 2.25 (width * length = area)

Answer 2

Answer:
`A=(9)/(16)\ m^2` (or
`\ 0.5625\ m^2`)

Step-by-step explanation:

The area of a rectangle can be calculated with the following formula:

`A=lw`

Where "l" is the lenght and "w" is the width.

In this case we know that the length of a flowerbed is 4 times as long as its width. This can be expressed as:

`l=4w`

We know that the width of the flowerbed is:

`w=(3)/(8)\ m`

Therefore, substituting the width into
`l=4w`, we get that the length is:

`l=4w\\\\l=4((3)/(8)\ m)\\\\l=(3)/(2)\ m`

Finally we can substitute the width and the lenght into the formula for calculate the area of a rectangle:

`A=((3)/(2)\ m)((3)/(8)\ m)\\\\A=(9)/(16)\ m^2`

(or
`\ 0.5625\ m^2`)
