He should place the picture at 6.75 inches from the edge of the wall.
<u><em>Explanation</em></u>
According to the below diagram, O is the center of the wall and <u>AB is the distance of the picture from the edge of the wall. </u>
As the length of the wall is
inches or 31.75 inches , so the half length of the wall
inches.
Now, the length of the picture is
inches or 18.25 inches, so the half length of the picture
inches.
Thus,
inches
So, he should place the picture at 6.75 inches from the edge of the wall.

The answer would be B. 8m.,
because if the base is 8, the height would be 6+8=14, and 14 x 8=112 x 1/2=56 m^2.
The dimensions of the scale drawing is length = 168 inches and width = 126 inches
<h3>How useful is a scale drawing?</h3>
Scale drawing helps to represent surfaces on earth in a paper by either enlarging its dimension, reducing its dimension by a constant factor called the scale factor.
The conversion or scale factor is 21 inches = 4 meters
If 21 inches = 4 meters,
then 1 meter = 21/4 inches
32 meters inches = 32 x 21/4 = 168 inches
24 meters = 24 x 21/4 = 126 inches.
In conclusion, length of the scale drawing is 168 inches and width of the scale drawing iss 126 inches
