Answer 1

Answer:

Step-by-step explanation:

Area of triangle can found by using these 2 formula

1.) 1/2×base×height

2.)s=a+b+c/2 after that

Under Root (s×a)-(s×b)-(s×c)

Answer 2

Hey friend!

Here is your answer:

Question: How to find the area of a triangle?

Method 1

When the length of the base and perpendicular to the opposite vertex is known.

Area of a triangle = ¹/₂ ₓ base ₓ height(or called altitude)

Method 2

When one angle is known length of two sides are known and the angle of opposite vertex is known.

Area of a triangle = ¹/₂ × a × b × sinC

Method 3

When the lengths of an isosceles triangle is given.

Area of a triangle is ¹/₄ × b × √(4a² - b²)

Method 4

When the triangle is an equilateral triangle.

Area of a triangle is √3/4 × a²

Method 5

When length of all the three sides of a triangle are known.

Area of a triangle is s√(s - a)(s - b)(s - c)

where s = (a + b + c)/2
