Question

find area of triangle with sides 120, 80 and 50 m

Answer 1

Given :-

• Sides of a triangle as 120m, 80m and 50m

To Find :-

• Area of the traingle.

Answer :-

• a = 120

• b = 80

• c = 50

S = a + b + c / 2

=> 120 + 80 + 50 / 2

=> 250/2

=> 125

Area of the triangle :-

$\sqrt{s(s - a)(s - b(s - c)}$

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

$\sqrt{125 \times 5 \times 40 \times 75}$

$\sqrt{1875000}$

$1369.30$

Hence, the area of the traingle is 1369.30m².

Answer 2

Answer:

use the formula,

area of a triangle=s√(s-a)(s-b)(s-c)

where a, b, c are the sides of the triangle
