ADD!

you are suppose to MULTIPLY on area.

You have to multiply to find area you have to add to find perimiter

Perimeter is most often found by adding.

To find the perimeter you add and to find the area we multiply.

You add the lengths of all sides of the shape.

you multiply the length by two then you multiply the width by two and then add the two answers 2l+2w

Perimeter: Add the length of the four sides. Area: Multiply length x width.

Perimeter: add all sides area: multiply length times width for rectangles

to find the perimeter you must add all sides. and to find area you have to multiply lenght and width

Area you multiply 2 sides and perimeter you add all the sides together.

perimeter means inside of shape and u addarea means outside of shape and u multiplyperimeter and area questions

for area you multiply length times width and for perimeter you add all of the sides together

To calculate the area you multiply the width times lenghth.the numbers that are on the side of the shape multiply them and you'll get the area. Now to get the perimeter you add the numbers on the sides together. Add lenght times width.that's how you get your perimter and area.

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.

No, you add up all the sides. Yes, in terms of a circle. To determine the perimeter or circumference of a circle, you must multiply: 2πr or two times Pi times the radius of the circle.

Perimeter = 2 x (length+width). You add the length to the width and multiply the sum by two.

Add the two known measurements together, then multiply by 2 - and you'll have your answer !

There are three simple ways to calculate the perimeter of a square.Add the length of all sidesAdd the height and width, and multiply the total times twoMultiply the length of any side times four.

For the area you just multiply base by height and divide by 2. For the perimeter you just add all the lengths together

Perimeter . . . add up the lengths of all three sides. Area . . . multiply (half the length of the base) by (the height).

deposit = add withdraw = subtract

The perimeter of an area or object is the total length of all sides. Measure each side with a ruler, yardstick, tape measure, etc... Add all of these numbers together, and you will have the perimeter.
