First, we have to find the area of the wall, then the area of the window, then subtract them.
Area of wall = 9 × 9 = 81 sq.unit
Area of window = 3 × 3 = 9 sq.unit
So, the area of the wall ( excluding window ), = 81 - 9 = 72 sq. unit

Step-by-step explanation:
Multiply the length by 2, then multiply the width by 2 and then add them together.
7 3/4 x 2 = 15 1/2
4 1/3 x 2 = 8 2/3
15 1/2 = 31/2
8 2/3 = 26/3
Find common denominator:
31/2 x 3 = 93/6
26/3 x 2 = 52/6
93/6 + 52/6 = 145/6
145/6 = 24 1/6 inches.
