The width of the rectangle is 3.
The area of the rectangle is 12 square units.
Explanation:
Given that the coordinates of the rectangle are A(3,0), B(0,0), C(0,4), D(3,4)
We need to determine the length, width and area of the rectangle.
<u>Length:</u>
After plotting the coordinates in the graph, it is obvious that the length of the rectangle is 4.
<u>Width:</u>
After plotting the coordinates in the graph, it is obvious that the width of the rectangle is 3.
<u>Area of the rectangle:</u>
The formula to determine the area of the rectangle is given by
Substituting the values, we have,
Thus, the area of the rectangle is 12 square units.
