youll have to split the shape up into three pieces. since 1/4 = 25 multiply that by 3 to get the length then multiply the length by the height (80) so 75 × 80 = 6000. then, the two boxes at the bottom divide the length that we got earlier 75/3 resulting in 25, so we multiply 25 by 20 giving you 500. multiply 500 by 2 giving you 1000 since theres two of the same boxes. and 6000+1000=7000 so the area is 7000.
