Question

Find area of triangle whose lengths are 17,15,21mts by herons formula and verify by 1/2 bh formula

Answer 1

Answer:

Step-by-step explanation:

Dear Student,

Answer:126.18 sq-m

Solution:

Heron's Formula:

Area of triangle =

here S is semi-perimeter of the triangle

here a,b and c are the sides of triangle

a = 15 m

b = 17 m

c = 21 m

Area

Area of triangle by heron's Formula = 126.18 sq-m

Since the given triangle is not right angle triangle so we can't apply 1/2 (base)(height ) formula.

and no additional information given about altitude of triangle.

Hope it helps you.
