Question

Problem solving in trig, help?

Answer 1

13170 to the nearest whole number.

Explanation:

We can use Heron's formula to do this:

Area = √[s(s-a)(s-b)(s-c)] where s = the semi-perimeter.

s = (155+175+260)/ 2

= 295

Therefore the Area = √ 295(295-155)(295-175)(295-260)

= √173460000

= 13170.42.
