Heron's formula is named after Hero of Alexendria, a Greek Engineer and Mathematician in 10 - 70 AD. You can use this formula to find the area of a triangle using the 3 side lengths.
Therefore, you do not have to rely on the formula for area that uses base and height. The picture below illustrates the general fro mu la where S represents the semi-perimeter of the triangle ,
Answer:
Area of given figure = 37.68 unit²
Step-by-step explanation:
Given:
Radius of given shape = 4 unit
Angle = 270°
Value of π = 3.14
Find:
Area of given figure
Computation:
Area of given figure = [Ф/360][πr²]
Area of given figure = [270/360][(3.14)(4)²]
Area of given figure = [0.75][(3.14)16]
Area of given figure = [0.75][50.24]
Area of given figure = 37.68 unit²
