Question

Find the area of a triangle whose sides are 5 m, 6 m and 9m,( use root 2 =-1.41 m)​

Answer 1

The area of the triangle is 14.1 square meters

How to determine the triangle area?

The side lengths are given as:

5m, 6m and 9m

Calculate the semi-perimeter (s) using

s = (5 + 6 + 9)/2

Evaluate

s = 10

The area is then calculated as:

$Area = \sqrt{s(s -a)(s-b)(s-c)$

This gives

$Area = \sqrt{10 * (10 -5)(10-6)(10-9)$

Evaluate the products

$Area = \sqrt{200$

Evaluate the exponent

Area = 14.1

Hence, the area of the triangle is 14.1 square meters
