Question

Calculate the area of this triangle.
14 cm
11 cm
18 cm

Answer 1

base x height divided by 2= 73cm

Answer 2

73 cm (Estimated)

Explanation:

Let's use hero's formula to solve this.

=> 1/2(14 + 11 + 18) = S

=> 1/2(43) = S

=> S = 21.5

√s(s - a)(s - b)(s - c)

=> √21.5(21.5 - 14)(21.5 - 11)(21.5 - 18)

=> √21.5 x 7.5 x 9.5 x 3.5

=> 73.2226911551 = Area of triangle

=> 73 cm² (Estimated)

Hoped this helped.
