Question

find the area of the triangle in which a=13m b=14 m c=15m​

Answer 1

Answer:

Area Of Triangle = 84m²

Step-by-step explanation:

We Have :-

Sides of Triangle as :-

a = 13m

b = 14m

c = 15m

To Find :-

Area of Triangle

Formula Used :-

Heron's Formula

Area = √ s ( s - a ) ( s - b ) ( s - c )

Solution :-

$Semi\ Perimeter = \frac{a + b + c}{2} \\\\= \frac{13 + 14 + 15}{2}\\ \\= \frac{42}{2} \\\\= 21 cm\\\\Area = \sqrt[]{s(s-a)(s-b)(s-c)} \\\\=\sqrt{21(21-13)(21-14)(21-15)}\\ \\=\sqrt{21(8)(7)(6)}\\ \\= \sqrt{7056} \\\\= 84 m^{2}$

Area Of Triangle = 84m²
