A right triangular field has its hypotenuse is fifty cm and one side is forty cm find the aarea of it triangle

You can use the pythagorean theorem (c^2=a^2+b^2, where "c" is the hypotenuse and "a" and "b" are the other sides) to find the length of the other side. Manipulate it to get c^2a^2=b^2, then take the square root of the answer to get the length of the other side. Then, use the formula for finding the area of a triangle (A=bh/2, where "b" is one side, and "h" is the other), to find the area.
Hope this helps!
