Area of Triangle given sides Solution

STEP 0: Pre-Calculation Summary

Formula Used

area = sqrt((Side A+Side B+Side C)*(Side B+Side C-Side A)*(Side A-Side B+Side C)*(Side A+Side B-Side C))/4
A = sqrt((S_a+S_b+S_c)*(S_b+S_c-S_a)*(S_a-S_b+S_c)*(S_a+S_b-S_c))/4
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - Squre root function, sqrt(Number)

Variables Used

Side A - Side A is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (Measured in Meter)
Side B - Side B is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (Measured in Meter)
Side C - Side C is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back. (Measured in Meter)

STEP 1: Convert Input(s) to Base Unit

Side A: 8 Meter --> 8 Meter No Conversion Required
Side B: 7 Meter --> 7 Meter No Conversion Required
Side C: 4 Meter --> 4 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = sqrt((S_a+S_b+S_c)*(S_b+S_c-S_a)*(S_a-S_b+S_c)*(S_a+S_b-S_c))/4 --> sqrt((8+7+4)*(7+4-8)*(8-7+4)*(8+7-4))/4

Evaluating ... ...

A = 13.9977676791694

STEP 3: Convert Result to Output's Unit

13.9977676791694 Square Meter --> No Conversion Required

FINAL ANSWER

13.9977676791694 Square Meter <-- Area

What is Area of a Triangle when sides and perimeter are given?

The area of a triangle when sides and perimeter are given, also known as Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria which states that area of a triangle can be found when the length of all three sides are known. According to Heron, we can find the area of any given triangle, whether it is a scalene, isosceles or equilateral, by using the formula, provided the sides of the triangle.

How to Calculate Area of Triangle given sides?

FAQ

What is Area of Triangle given sides?

Area of Triangle given sides is defined as the total region that is enclosed by a particular triangle with a given sides and is represented as A = sqrt((S_a+S_b+S_c)*(S_b+S_c-S_a)*(S_a-S_b+S_c)*(S_a+S_b-S_c))/4 or area = sqrt((Side A+Side B+Side C)*(Side B+Side C-Side A)*(Side A-Side B+Side C)*(Side A+Side B-Side C))/4. Side A is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back, Side B is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back & Side C is an upright or sloping surface of a structure or object that is not the top or bottom and generally not the front or back.

How to calculate Area of Triangle given sides?

Area of Triangle given sides is defined as the total region that is enclosed by a particular triangle with a given sides is calculated using area = sqrt((Side A+Side B+Side C)*(Side B+Side C-Side A)*(Side A-Side B+Side C)*(Side A+Side B-Side C))/4. To calculate Area of Triangle given sides, you need Side A (S_a), Side B (S_b) & Side C (S_c). With our tool, you need to enter the respective value for Side A, Side B & Side C and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
