Given data:

The legs of the triangle with legs that are 15m , 25m and 20m

The legs given are the sides of right angle triangle, we can see this by


\begin{gathered} \text{Hypotenues}^2=Perpendicvular^2+Base^2 \\ (25)^2=(15)^2+(20)^2 \\ 625=225+400 \\ 625=625 \end{gathered}

Therefore, from above it is clear that the perpendicular side is the height that is 15m and base is 20m

Area of triangle,


\begin{gathered} A=(1)/(2)* base* height \\ =(1)/(2)*15*20 \\ =150m^2 \end{gathered}

Thus, the area of triangle is 150 meter square.
