Detailed Solution

Concept- We have a rectangle, and the graphic also shows the rectangle's measurements. We must apply the formula ${"mathml":"<math class="image_resized" style="width:56px;height:11px"><span style="font-family:$ , where l is the rectangle's length and b is its width, to get the area of the rectangle.

As a result, we may depict the resulting rectangle as in the image above.
Therefore, it is evident that the rectangle's width is equal to 4 meters and its length is equal to 7 meters.
${"mathml":"<math class="image_resized" style="width:78px;height:40px"><span style="font-family:$ We are aware that if a rectangle's length and width are both equal to l and b, then the area of the rectangle is equal to the sum of l and b.
Assume that A is the same as the rectangle's area.
${"mathml":"<math class="image_resized" style="width:56px;height:11px"><span style="font-family:$ When we replace equations (1) and (2) in equation (3) , we obtain
${"mathml":"<math class="image_resized" style="width:57px;height:37px"><span style="font-family:$ Hence, the correct option is 4) 28 ${"mathml":"<math class="image_resized" style="width:25px;height:13px"><span style="font-family:$
