The area is the inside. The perimiter is around. If its a rectangle, to find the area you multiply the lengths of two sides

simply to find area,distance, and perimiter

it is the area of a solid object times by the square root of the perimiter

area is inside and and perimeter is outline.

To find the area of a triangle, you have to multiply the base of the triangle and the height of the triangle, then divide the product of those numbers by two.

perimiter

99 inches.

If the area is that of a circle or a regular polygon (triangle, square, reg pentagon etc) there are formulae that will enable you to do so. If it is any other shape - ellipse, irregular polygon, or worse still a random shape - then the area cannot be found.

It is actually impossible to work out the square root of a shape but you can work out the square roots of the interior and exterior angles, the area and the perimiter
