we know that

Triangle MOL is an isosceles triangle

because


MO=OL=radius\ of\ circle=25\ units


ON=25\ units


ON=OP+PN\\ 25=OP+10\\ OP=25-10\\ OP=15\ units

Find the base MP

Applying the Pythagorean Theorem in the right triangle MPO


MO^(2) =MP^(2)+PO^(2)\\ MP^(2)=MO^(2)-PO^(2)\\ MP^(2)=25^(2)-15^(2)\\ MP^(2)=400\\ MP=20\ units


ML=2*MP\\ ML=2*20\\ ML=40\ units

Find the area of triangle MOL


A=(1)/(2)ML*PO\\ \\ A=(1)/(2)*40*15\\ \\ A=300\ unit^(2)

therefore

the answer is

the area of triangle MOL is


300 square units
