I have four sides all of 3 cm.

The perimeter, in feet, is 8.5 times the number of sides.

The perimeter of a rectangle is just the sum of the lengths of its sides, so taking half of each of the sides would make the total half of its original value also.

the perimeter is all of the sides added up, the length and width would only give you half of the perimeter i think...

Perimeter is just the measure around the outside of the figure. The square has to have all the sides of equal length, so they must be 25 feet (25x4=100) The rectangle needs to have 2 sides of equal length and 2 sides of a different equal length. They could be 30 ft, 30 ft, 20 ft, 20 ft....or 45 ft, 45 ft, 5 ft, 5 ft,. As long as the first 2 sides together equal more than 50 ft (more than half), then the last two sides equal (100-first two sides) divided by 2 sides.

26 feet (4 sides x 6.5 = 26)

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

Perimeter of the isosceles triangle: 16.2+16.2+8.1 = 40.5 cm

The two sides are each 3086 centimeters in length. An isosceles triangle has a base and two congruent sides. If the base of an isosceles triangle is 43 cm long and the perimeter of that triangle is 6215 cm, then the length of the two congruent sides is 6215 cm minus 43 cm, or 6172 cm. Each side will be half that, or 6172 cm divided by 2, or 3086 cm.

draw a quadrangle measure the sides to the nearest half inch writ the length next to each side .find the perimeter

Ten tenths equal 1. So to find half of that, devide both sides by 2; you end up with 5 tenths equal one half.

Sum the measurements of the sides. If the letter is symmetrical you can measure half and multiply by two.

So what?

Perimeter = diameter x pi. Area = pi x radius2. (The radius is half the diameter.)

The perimeter of the rectangle is the sum of all four side lengths. A rectangle has two pairs of congruent sides. Two sides are 8m each. That accounts for 16m of the perimeter. 22 - 16 = 6. So the other two sides must add up to 6m. Divide that amount in half since the sides are congruent. The width of the rectangle is 3m.

All you would have to do is multiply 2.5 by 4 since a square is composed of 4 sides and all a perimeter is is the measure of the outside of a shape.

The perimeter of a full circle is 2*pi*r. Where, pi is the mathematical constant that is the ratio of any circle's circumference to its diameter, approximately equal to 3.14, and r is the radius of the circle. The perimeter of a semi circle, assumed to be half of a full circle is pi*r where pi and r are previously defined.

The answer will be 30.25

Input straight line joining mid -point of any two sides of triangle is parallel to the 3rd side and equal to half of it.

The area of a regular polygon with n sides is the half of the product of its perimeter and the apothem. So that you do not have enough information to find the area of the polygon (for example how many sides it has, or the side length).

11 sides of 4.5 inches each sums to 49.5 inches = 4 ft 1.5 inches.

The area of a circle is equal to the perimeter times half the radius. That is, A = P*r/2

Measure the length of the 4 sides. If equal, you have an equilateral rectangle and can multiply length X width for the area. If not equal, then find the rectangle and measure as above, then measure the remaining 1 or 2 right triangles at the base and altitude, multiply, divide by half, and add all together.
