Question

Find the area of the triangle 9 yd, 3 yd and 8 yd

Answer 1

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

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

Where,

$s=\frac{a+b+c}{2}$

The value s for given triangle is

$s=\frac{9+3+8}{2}=10$

The area of given triangle is

$A=\sqrt{10(10-9)(10-3)(10-8)}$

$A=\sqrt{10(1)(7)(2)}$

$A=\sqrt{140}$

$A=11.8321595662$

$A\approx 11.83$

Therefore the area of given triangle is 11.83 square yd.

Answer 2

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.
