The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.

The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width. You will often encounter word problems where two of the values in one of these formulas are given, and you are required to find the third. Example 1: The perimeter of a rectangular pool is 56 meters.

Add l + l + w + w. Instead of adding two sides of your rectangle and multiplying by two, you can simply add all four sides together directly to find the perimeter of your rectangle.

['Remember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)', 'Substitute the known values into the area formula. 36 = 4 * w. ... ', 'Substitute values for length and width into the perimeter formula.']

['In the given triangle, a, b and c are the sides of the triangle. Perimeter of a triangle.', 'Perimeter of triangle = a + b + c. ... ', 'Here, sides of the triangle are AB = 3 cm, BC = 4 cm and AC = 3 cm. ... ', 'Perimeter of an isosceles triangle = a + b + c. ... ', 'Perimeter of an equilateral triangle = a + b + c.']

To find the perimeter, add together the lengths of the sides. Start at the top and work clockwise around the shape. Area of Polygon = (Area of A) + (Area of B) To find the area, divide the polygon into two separate, simpler regions.

Step 1: Remember that perimeter is the measure of the outer edge of a shape, or otherwise, the sum of the measures of the sides of the trapezoid. Representing the perimeter by P, and the sides as a, b, c and d, our formula is P= a + b + c + d.

In order to find the perimeter of a square from the area find what number multiplied by itself gives you the area of the square. then you multiply that number by 4 to get the perimeter because all sides of a square are the same length.

['Plot the coordinates. The first number tells the x value while the second number is the y value. ... ', 'Connect the dots and identify the figure. The connected points show a square.', 'Determine lengths. By counting the grid lines we see that the sides = 3.', 'If a formula exists, use it to find the perimeter and the area.']

The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

To find the perimeter, add every side of the shape to find the total. If one or more sides are fractions, you will have to follow the rules for adding fractions to add each side and find the perimeter.

Correct answer: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides.
