It is not possible to answer the question because it is not clear what the three measures represent.
If it's a right triangle the formula for area is 1/2base times the height. so 1/2(15)(20) which is 10 times 15 so the answer would be 150.

A cylinder with a surface area of 200cm2 and a height of 20cm has a volume of about 137.96cm3

Oh, dude, you're hitting me with the math questions, huh? So, to find the area of a triangle, you use the formula: 0.5 x base x height. In this case, the base is 8cm and the height is 10cm, so the area would be 0.5 x 8 x 10 = 40 square centimeters. But those side lengths you mentioned? They're just there to confuse you; we don't need 'em for this calculation.
180 cm2
Its 20cm

It will have 3 equal sides of 20cm Using Pythagoras's' theorem its height is 17.32050808cm Using the formula for area:1/2*base*height its area is 173.32050808cm2

better question what shape is it
