Here, In Right angle triangle, base = 12 m height = 8 mNow, ◇ Area = 1/2*b*h = 1/2*12*8 = 48 m^2In semicircle, radius = 4 m Then, ◇Area" = 1/2*22/7*r^ = 1/2*22/7*4*4 = 25.14m^2Again,◆Total Area = Right triangle + semicircle = (48+25.14) m^2 = 73.14 m^2This is right answer...I hope you understand...Mark me as brainliest...Thank you ♥♥
