Area of Rectangle on the Left = length*width = c*d = 24*20 = 480 Area of Rectangle in the center = length*width = c*b = 24*10 = 240 Area of Rectangle on the Right = length*width = c*e = 24*17 = 408
Area of top triangle = (base*height)/2 = b*a/2 = 10*17/2 = 170/2 = 85 Area of bottom triangle = (base*height)/2 = b*a/2 = 10*17/2 = 170/2 = 85
Add up the individual areas to get: 480+240+408+85+85 = 1298
The units are in square feet since this is dealing with area.
