Question

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

Answer 1

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 2

The area of given triangle is 11.83 square yd.

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=√(s(s-a)(s-b)(s-c))`

Where,

`s=(a+b+c)/(2)`

The value s for given triangle is

`s=(9+3+8)/(2)=10`

The area of given triangle is

`A=√(10(10-9)(10-3)(10-8))`

`A=√(10(1)(7)(2))`

`A=√(140)`

`A=11.8321595662`

`A\approx 11.83`

Therefore the area of given triangle is 11.83 square yd.
