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: $A=\frac{9}{16}\ m^2$  (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:

$w=\frac{3}{8}\ m$

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

 $l=4w\\\\l=4(\frac{3}{8}\ m)\\\\l=\frac{3}{2}\ m$

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

$A=(\frac{3}{2}\ m)(\frac{3}{8}\ m)\\\\A=\frac{9}{16}\ m^2$

(or $\ 0.5625\ m^2$)
