Respuesta :

The area is base times height divided by 2 so 4.5 x 3 or 8 since I need a picture to see which sides are measured as which.

Answer:

The area of given triangle is 11.83 square yd.

Step-by-step explanation:

Given information: Measure of three sides of a triangle are 9 yd, 3 yd and 8 yd.

According to Heron's formula: If a,b and c are three sides of a triangle, then the area of a triangle is

[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where,

[tex]s=\frac{a+b+c}{2}[/tex]

The value s for given triangle is

[tex]s=\frac{9+3+8}{2}=10[/tex]

The area of given triangle is

[tex]A=\sqrt{10(10-9)(10-3)(10-8)}[/tex]

[tex]A=\sqrt{10(1)(7)(2)}[/tex]

[tex]A=\sqrt{140}[/tex]

[tex]A=11.8321595662[/tex]

[tex]A\approx 11.83[/tex]

Therefore the area of given triangle is 11.83 square yd.
