Heather clears a rectangular region in her yard for a garden. if the length is a one-digit whole number and the width is 5.5 meters, what is the least possible area? what is the greatest possible area? what is the greatest possible area? explain how you found your answers.

Least possible area is 5.5 m² and greatest possible area is 49.5 m².

Step-by-step explanation:

∵ Area of a rectangle = length × width,

Let x be the length ( in meters ) of the rectangular garden,

We have, width of the garden = 5.5 meters,

So, area of the rectangle,

A = 5.5x

If x = one-digit whole number,

Then x = {0, 1, 2, 3, 4, 9}

If x = 0, A = 0 ( not possible ),

Thus, least area would be possible if x = 1 meter,

So, least possible area of the garden, A = 5.5 m²,

While, greatest area would be possible if x = greatest i.e. 9 meter,

So, greatest possible area of the garden, A = 5.5 × 9 = 49.5 m²

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
