Answer:
Explanation:
We can use the Heron's Formula to calculate the area of the triangle, yet first we need to calculate half the perimeter of the triangle
The sides are a= 11, b=9.7, c=4.6
Half of the perimeter is
s = (a+b+c)/ 2 = (11 +9.7 +4.6)/2 = 25.3/ 2 = 12.65 inches
Heron's Formula for calculating the area of the triangle:
A = √(s (s -a)(s -b)(s -c))
A = √(12.65* (12.65 -11)(12.65 -9.7)(12.65-4.6))
A = √(12.65* 1.65 * 2.95 *8.05)
A ≈ 22.26 inc.²
