Question

Find the area of a triangular field whose sides are 50m, 45m, 35m

Answer 1

Answer:

Required Answer:-

Here sides are=50,45,35

$s={(a+b+c)}/2={\dfrac {(50+45+35)}{2}}={\dfrac {130}{2}}=65$

use herons formula

${\sqrt {s (s-a)(s-b)(s-c)}} \\ ={\sqrt {65 (65-50)(65-45)(65-35)}} \\ ={\sqrt {65 ×15×20×30}} \\ ={\sqrt {585000}} \\ =83.63m {}^{2}$

• Area =83.63m^2
