Question

Find the area of triangle two side of which are 80m and 50 m
and the perimeter is 250m.​

Answer 1

Answer:

Perimeter = a + b + c

250m = 80m + 50m + c

c = 250m - [80m +50m]

c= 250m - 130m

c= 120m

using herons formula

s = 250m/2

     125m

area = $\sqrt{}$s[s-a][s-b][s-c]

        ( $\sqrt{}$125[125-80][125-50][125-120] )m²

        375$\sqrt{15}$ m²
