Step-by-step explanation:
(5 + 7x + 6)/2 = 3x + 9
7x + 11 = 6x + 18
7x - 6x = 7
x = 7
EF = 3x + 9
= 3(7) + 9
= 21 + 9
= 30
Area of the four walls = 2(Length x height) + 2(Width x height)
Area of the four walls = 2(21 x 28) + 2(13 x 28)
Area of the four walls = 1176 + 728
Area of the four walls = 1904 in²
