Add together the 4 sides
The area is the inside. The perimiter is around. If its a rectangle, to find the area you multiply the lengths of two sides
21
2*l+2*22/7*r
28
Add up the sides.
to find the perimiter you just add up all the sides....Perimiter is the same for every figure.
Add together the 4 sides
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.
2 * pi * r
C = (pi)/d or c = 2(pi)r.
Run a piece of string round the edge and then measure it
The perimeter is 31.11 units.
simply to find area,distance, and perimiter
Add the lengths of any two adjacent sides, and double the sum.
it is the area of a solid object times by the square root of the perimiter
you can usally find gekos in big shady trees that are big around the perimiter. you can also find them on a brick wall in your BACKyard.
