[RESOLVED] Find Area Of A Triangle (Without Calculator)

[03myersd]

I am possibly bein a very big dunce here but I am wondering how you would solve this problem. I am currently in school and revising for exams and i came accross a problem that i couldn't figure out how to solve. I would ask a teacher except its the holidays. I was wondering if anyone could shed some light on the solution. A calculator cannot be used at all. Thanks. Attachment 55982

Yeah I was being thick. I now realise that all i had to do was turn it on its side..... Oh well easy done i suppose?

10 x 20 / 2 = 100.

Now, suppose it was not a right triangle. Then you have a more difficult problem to solve.

Actually, the teacher gave you more information than you needed. Once the right angle was specified, the length of any third side was determined by the other two.

Although you do, of course, realise that with the lengths specified there, that is not actually a right-angled triangle...

[Code Doc]

ZaZa is correct. Side BC should be 15.

Chief Big Bear married a squaw who bore 3 sons and lived on a deer hide. He next married another squaw who bore 4 sons and lived on a buffalo hide. He finally married another squaw who bore 5 sons and lived on a hippopotamus hide.

That proves that the square of the sons of the squaw on the hippopotamus hide equals the sum of the squares of the sons of the squaws on the other two hides.

If you call m,n the 2 segments of the base at either side of the projection of the height h, you can set up a system of equations

h² + m² = 20²
h² + n² = 10²
m + n = 25

which can be solved very easily. Thereafter the area follows:

Area = 25*h / 2
