As we know the formula of area of rectangle
Let 25 units is width of rectangle
Area = 1,125
units
Dimension of rectangle 45 x 25.
Now we draw the grid graph of rectangle.
First we take a grid paper with 1 square unit area of each box. Now we draw line with 45 unit horizontal(Length) and 25 unit vertical (Width).
We make a closed figure with four line opposite side equal and parallel.
Inside box, total number of box must be 1,125 because area of 1 small box 1 square unit.
Total area of all box = 1,125 x 1 = 1,125 square units.
