Drow two different rectilinear shapes each with an area of 6 squares.

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.
