Height of the wall = 8 2/5 ft
Height of the wall = 42/5 ft
The length of the wall = 16 2/3 ft
The length of the wall = 50/3 ft
The area of the wall = 42/5 x 50/3
The area of the wall = 14 x 10
The area of the wall = 140 square feet
Half of the wall was painted blue
Area of the wall painted blue = 140/2
Area of the wall painted blue = 70 square feet
