Question

Find the area of the isosceles triangles with side lengths 16 meters, 17 meters, and 17 meters.

Answer 1

120 meters

Explanation:

The triangle area using Heron's formula

Heron's formula gives the area of a triangle when the length of all three sides is known. There is no need to calculate angles or other distances in the triangle first. Heron's formula works equally well in all cases and types of triangles.

`T=√(s(s-a)(s-b)(s-c)) \\`

`T=√(25(25-17)(25-17)(25-16))`

`T=√(14400) =120`
