Find the distance of each side and add to find the total perimeter.
To find perimeter you would add all of the sides of your object together to get the final result.
920 mm. Because since an octagon has 8 sides and they are all 115 in length, to find the total perimeter simply add up 115 8 times, or multiply 115 by 8.
If that's a rectangle, the perimeter is 24 inches and the area is 27 square inches.
To find the distance around a figure, you calculate the perimeter. The perimeter is the total distance around the outside of a shape or figure. To find the perimeter of a rectangle or square, you add up all the sides. For a circle, you can find the perimeter by multiplying the diameter by π (pi).
To find the perimeter you add and to find the area we multiply.
Multiply for the area, add for the perimeter.
You add for perimeter...
You add the lengths of all sides of the shape.
to find the perimeter you must add all sides. and to find area you have to multiply lenght and width
You have to multiply to find area you have to add to find perimiter
you multiply the length by two then you multiply the width by two and then add the two answers 2l+2w
The formula for perimeter is 2l+2w or 2*length + 2*width. This means that you multiply the length by two and multiply the width by two. Then, you add the two products together to find the perimeter.
for area you multiply length times width and for perimeter you add all of the sides together
Perimeter is most often found by adding.
Perimeter = 2 x (length+width). You add the length to the width and multiply the sum by two.
you just take the length of it's midsegment and multiply it by its height to find area. to find it's perimeter, just add the measures of it's sides
