Answer:

70

Step-by-step explanation:

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
