Question

the peremeter of a triangle field is 40 m, if two sides of that field are 8m and 14m, then find the area of field.​

Answer 1

hey mate

here is your answer

third side =40-22=18

by heron's formula

semi perimeter =20 m

$\sqrt{20(20 - 18)(20 - 14)(20 - 8)} \\ = \sqrt{20 \times 2 \times 6 \times 12} \\ = \sqrt{10 \times 2 \times 2 \times 6 \times 6 \times 2} \\ = 6 \times 2 \times 2 \sqrt{5} \\ = 24 \sqrt{5}$

=53.52
