To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.

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

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.

the area is 18

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.

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
