: **a flat geometric figure of four sides and four angles**. quadrilateral.

If we suppose the length of a rectangle is L and breadth is B, the length of the diagonal = **√L2+B2**. Area of Rectangle = L × B. Perimeter of Rectangle = 2(L+B)

We know that the perimeter of the quadrilateral = the sum of all the sides of the quadrilateral ABCD = (AB + BC + CD + DA). We have all the values for the sides, so we get the perimeter as, = (8 + 5 + 13 + 10) cm = **36 cm**.

A quadrilateral is **a closed shape and a type of polygon that has four sides, four vertices and four angles**. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees.

The perimeter of a quadrilateral is **the total length of its boundary**. For example, the perimeter of a quadrilateral ABCD can be expressed as, Perimeter = AB + BC + CD + DA. This means if all the sides of a quadrilateral are known, we can get its perimeter by adding all its sides.

We have found that area of a quadrilateral ABCD in which AB = 3 cm, BC = 4 cm, CD = 4 cm, DA = 5 cm and AC = 5 cm is **15.2 cm ^{2}**.

Use the Numerators

Your total, and your perimeter, will be 26/12. **If you have a shape with even sides and use a multiplication formula, only multiply the numerator**. For example, to find the perimeter of a square with the formula P=4x, and your side length is 3/4, multiply 3x2 and put the product over 4.

**Quadrilaterals: Classification**

- A quadrilateral is a polygon with four sides.
- A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals.
- A rhombus is a parallelogram with four congruent sides.
- A trapezoid is a quadrilateral with exactly one pair of parallel sides.

**Use the law of sines or the law of cosines to calculate the lengths of the sides of a triangle and quadrilateral** (a quadrilateral is essentially two adjacent triangles) if you know the measure of one side, one angle and one additional side or angle.

The area of any cyclic quadrilateral ABCD is given by **A2=(s−a)(s−b)(s−c)(s−d)**, where 2s=a+b+c+d,where a,b,c, and d are the sides of the quadrilateral.

A quadrilateral has 4 sides, **4 angles** and 4 vertices. A quadrilateral can be regular or irregular. The sum of all the interior angles of a quadrilateral is 360°.

**Rectangle**. A rectangle has two pairs of equal sides.

: **a flat geometric figure of four sides and four angles**. quadrilateral.

The area of the triangle ABD = (1/2) × d × h2 h 2 . From the above figure, the area of the quadrilateral ABCD = **area of ΔBCD + area of ΔABD**. Thus, the area of the quadrilateral ABCD = (1/2) × d × h1 h 1 + (1/2) × d × h2 h 2 = (1/2) × d × (h1+h2 h 1 + h 2 ).

**Plants and animals** are the main source of food for all the organisms on earth. Food obtained from animals is the main source of protein and include fish, milk, meat, poultry, and cheese. Whereas plants provide us with fruits and vegetables, which are an important source of fibres, proteins and carbohydrates.

According to Ohm's Law, **Current Increases** when Voltage increases (I=V/R), but Current decreases when Voltage increases according to (P = VI) formula.

A Quick Overview. The following video provides an outline of all the topics you would expect to see in a typical Multivariable Calculus class (i.e., **Calculus 3, Vector Calculus, Multivariate Calculus**). All the topics are covered in detail in our Online Calculus 3 Course.

Answer. **Two versions** of the Internet Protocol are in common use in the Internet today. The original version of the Internet Protocol for use in the Internet is Internet Protocol Version 4, first installed in 1983.

**Use virtual local area networks (VLANs)** to logically separate network traffic and functions, and firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS) and routers to monitor and filter inbound and outbound traffic.
