Answer:
We can draw a rectangle and a square.
First the square:
The area of a square of sidelength L is:
A = L^2
So if the area of this square must be 6 square units, we get:
6 square units = L^2
L = √(6 square units) = 2.45 units
Now for a rectangle, we know that for a rectangle of length L and width W, the area is:
A = L*W
Now let's give the width a value of 1 unit, then W = 1unit
A = L*1 unit
And we know that the area must be of 6 square units, then:
6 square units = L*1 unit
(6 square units)/(1 unit) = L
(6 units) = L
The drawings (these are not exact ones, i'm doing them with a mouse) of the images can be seen below.
