Question

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

Answer 1

Explanation:

You can use Heron's formula for this question.

Heron's Formula: Area of Triangle = root s(s-a)(s-b)(s-c)

Where s = perimeter/2 and a, b, and c are the side lengths.

So solving...

s = perimeter/2

= (9yd + 3yd + 8yd)/2

= 20yd/2

= 10yd

A = root 10yd(10yd-9yd)(10yd-3yd)(10yd-8yd)

= root 10yd(1yd)(7yd)(2yd)

= root 140yd

= 2 root 35
