## What is the area of cyclic quadrilateral?

The area of a cyclic quadrilateral is K=√(s−a)(s−b)(s−c)(s−d) where a, b, c, and d are the four sides of the quadrilateral, and s, the semi perimeter, is defined as s = (1/2)×(a+b+c+d).

**What is the Heron area formula?**

Heron’s formula, formula credited to Heron of Alexandria (c. 62 ce) for finding the area of a triangle in terms of the lengths of its sides. In symbols, if a, b, and c are the lengths of the sides: Area = Square root of√s(s – a)(s – b)(s – c) where s is half the perimeter, or (a + b + c)/2.

**Can herons formula be used to calculate area of quadrilaterals?**

Heron’s formula cannot be used in finding the area of quadrilateral.

### What is the formula of quadrilateral in Heron’s formula?

He discovered The formula which is known as Heron’s formula. Heron’s formula can be utilised to calculate the area of the triangles, quadrilaterals. The Heron’s formula is articulated as \(s=\frac{a+b+c}{2}\). Here the letter “s” indicates the semi perimeter of the triangle.

**What is the formula of perimeter of cyclic quadrilateral?**

Solution: Given the measurement of the sides are, 4 cm, 2 cm, 6 cm, and 8 cm. Therefore, the perimeter of a cyclic quadrilateral = 2s = 20.

**What is Heron’s formula Class 10th?**

By Heron’s formula. Area of triangle Area of ABCD = Area of ABC + Area of ACD. = (6 + 9.166) cm2 = 15.166 cm2 = 15.2 cm2 (approximately) For triangle I. This triangle is a isosceles triangle.

#### What is Heron’s formula with example?

Step 1: Find the perimeter of the given triangle. Step 2: Find the semi-perimeter by halving the perimeter. Step 3: Find the area of the triangle using Heron’s formula √(s(s – a)(s – b)(s – c)). Step 4: Once the value is determined, write the unit at the end (For example, m2, cm2, or in2).

**What is the formula of the area of a quadrilateral?**

Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.

## What is the area of a cyclic quadrilateral given the measurement of the sides as 11cm 5cm 4cm and 8cm?

Given a cyclic quadrilateral whose sides are 4 cm, 5 cm, 8 cm, and 11 cm. Its area is: A. 40.25 sq.

**What is Heron’s formula 9?**

Area of a triangle using Heron’s Formula = A = √{s(s-a)(s-b)(s-c)}, where a, b and c are the length of the three sides of a triangle and s is the semi-perimeter of the triangle given by (a + b + c)/2.
