how to find the area of perimeter
Answers
Answer:
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.
Answer:
Area and Perimeter is an important topic in Mathematics, which is used in everyday life. This is applicable for any shape and size whether it is regular or irregular. You must have learned about different shapes such as triangle, square, rectangle, circle, sphere, etc.
Area and Perimeter Chart
Here is the list of all the area and perimeter for different figures in a tabular form. Students can use this table to solve problems based on the formulas given here.
Shape Area Perimeter Terms
Circle A = π × r2 Circumference = 2πr r = radius of the circle
Triangle A = ½ × b × h S = a+b+c b = base
h = height
a,b and c are the sides of the triangle
Square A = a2 P = 4a a = length of side
Rectangle A = l × w P = 2(l + w) l = length
w = width
Parallelogram A = b × h P = 2(a+b) a = side
b=base
h=vertical height
Area and Perimeter Formulas For all Shapes
There are many types of Shapes. The most common ones are Square, Triangle, Rectangle, Circle etc. To know the area and perimeter of all these, we need different formulas.
Perimeter and Area of a Rectangle
A rectangle is a figure/shape with opposite sides equal and all angles equal to 90 degrees. The area of the rectangle is the space covered by it in an XY plane.
Area and Perimeter 1
Perimeter of a Rectangle = 2(a+b)
Area of Rectangle = a × b
where a and b are the length and width of the rectangle.
Perimeter and Area of a Square
A Square is a figure/shape with all four sides equal and all angles equal to 90 degrees. The area of the square is the space occupied by the square in a 2D plane and its perimeter is the distance covered on the outer line.
Area and Perimeter 2
Perimeter of a Square = 4a
Area of a Square = a2
where a is the length of the side of the square.

Perimeter and Area of Triangle
The triangle has three sides. Therefore, the perimeter of any given triangle, whether it is scalene, isosceles or equilateral, will be equal to the sum of the length of all three sides. And the area of any triangle is the space occupied by it in a plane.
Area and Perimeter 3
Perimeter of a triangle = a + b +c , where a, b and c are the three different sides of the triangle.
Area of a triangle = 1/2 b × h; where b is the base and h is the height of the triangle.
Area and Circumference of Circle
Area of a circle is the region occupied by it in a plane.
Area and Perimeter 4
In case of a circle, the distance of the outer line of the circle is called the circumference.
Circumference of Circle = 2πr
Area of Circle = πr2
