I have a triangular table which has sides of 20,25 & 50 inches.What is the area of the table?

Area is zero, since 50 > 20 + 25. Can't form a triangle with those sides. However if you misheard this one, and it's really 20, 25, and 15 inches, that forms a right triangle of proportions 3, 4, 5, and the area of this triangle would be 1/2 (15)(20), or 150 square inches.

The area of a triangle is equal to 1/2 * BASE*HEIGHT.
1/2bh
But since 20 and 25 is equal to 45 you must have measured wrong because you triangle table, would have to be a straight line.

Urm, I hate to tell you this dude, but I think it's impossible to have a triangle table that way...
If the sides are 20:25:50 inches,
then the ratio would be 4:5:10 inches.
If you don't believe me, you can try plotting the triangle of the above ratio in cm in a graph paper....
It's... Impossible...

Those three lengths can't form a triangle. This is obvious: no mater how wide you open up one side of 20 and another of 25, the longest third-side they could make would approach 45.

Impossible, the longer side is too big. Should be less than the sum of the 2 smaller ones.

Cannot form a triangular table of those dimensions on this planet. Sorry.

my math's a lil rusty but if im not wrong,
using cosine rule, u can find one of the 3 angles, i found the one angle between 20 and 25, and it's 137.5 degrees,
then, use the sine rule [1/2xAxBxsinc] and u'll get area to be 168.9 inches squared.
ps correct me if im wrong.
