How do you calculate the total area of a rectangle?

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

How do you find the total area of a square?

The area of a square is calculated with the help of the formula: Area = s × s, where, ‘s’ is one side of the square. Since the area of a square is a two-dimensional quantity, it is always expressed in square units.

How do you calculate area of an irregular shape?

To calculate the Area of Irregular Shapes, divide the Shape with curves into two or more Regular Shapes. In this method, divide an Irregular Shape into multiple Squares, triangles, or other Quadrilaterals.

What is area formula?

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

How do you find the area of a variable?

How do you find the area with 4 different sides?

The area of any irregular quadrilateral can be calculated by dividing it into triangles. Example: Find the area of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.

How do you find the area of an irregular shape with 4 sides?

To find the area of such irregular quadrilaterals, follow a three-step strategy:
  1. Divide the quadrilateral into two triangles by constructing a diagonal that does not disturb the known interior angle.
  2. Calculate the area of each triangle, using formulas.
  3. Add the areas of the two triangles.

What shape has 4 sides of different lengths?

Quadrilaterals
Quadrilaterals are polygons with four sides (hence the beginning “quad”, which means “four”). A polygon with non-equal sides is called irregular, so the figure that you are describing is an irregular quadrilateral. This figure has side lengths of 1, 2, 3, and 4 respectively, so it is an irregular quadrilateral.

How do you find the area of an irregular shape with 6 sides?

area = (base * height) / 2.

What is the area of quadrant?

The formula for the area of a quadrant is 1/4 × area of a circle or is equal to πr2/4. And the units for area of quadrant is m2, inch2, cm2.

What does a pentagon look like?

A pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a is a five-sided polygon with five straight sides and five interior angles, which add up to 540°. Pentagons can be simple or self-intersecting.

Is there a 2 sided shape?

In geometry, a digon is a polygon with two sides (edges) and two vertices. … The digon is the simplest abstract polytope of rank 2. A truncated digon, t{2} is a square, {4}. An alternated digon, h{2} is a monogon, {1}.

What is a pentagon shape?

In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.

Is a starfish A pentagon?

Starfish: Almost all starfish have a fivefold radial symmetry or are shaped like pentagons.

Can a pyramid have 5 sides?

In geometry, a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the vertex). Like any pyramid, it is self-dual.
