Question

If the area of the rectangle to be drawn is 12 square units, where should points C and D be located, if they lie vertically below A and B, to make this rectangle?

Answer 1

C(2,-2), D(-1,-2)

Explanation:

The area of a rectangle is calculated using the formula:

`A=L* W`

• From the graph, AB = 3 units.

,

• Given that the area = 12 square units

`\begin{gathered} 12=3* L \\ L=(12)/(3)=4 \end{gathered}`

This means that the distance from B to C and A to D must be 4 units each.

Count 4 units vertically downwards from A and B.

The coordinates of C and D are:

• C(2,-2)

,

• D(-1,-2)

The first option is correct.
